Download or read book Multi-Carrier and Spread Spectrum Systems written by Khaled Fazel and published by John Wiley & Sons. This book was released on 2008-09-15 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The technological progress in multi-carrier (MC) modulation led orthogonal frequency division multiplexing (OFDM) to become an important part of beyond 3G cellular mobile communication standards, including LTE and WiMAX. In addition, the flexibility offered by the spread spectrum (SS) and time division multiplexing (TDM) techniques motivated many researchers to investigate several MC combined multiple access schemes, such as MC-CDMA, OFDMA and MC-TDMA. These schemes benefit from the advantages of each sub-system and offer high flexibility, high spectral efficiency, simple detection strategies and narrow-band interference rejection capability. Multi-Carrier and Spread Spectrum Systems is one of the first books to describe and analyze the basic concepts of multi-carrier OFDM transmission and its combination with spread spectrum (MC-CDMA). The different architectures and detection strategies as well as baseband-related transceiver components are explained. This includes topics like FEC channel coding and decoding, modulation and demodulation (IFFT/FFT), digital I/Q-generation, time and frequency synchronisation, channel estimation, frequency domain equalization and RF aspects such as phase noise and non-linearity issues. Concrete examples of its applications for cellular mobile communication systems (B3G/4G) are given. Further derivatives of MC-SS (such as OFDMA, SS-MC-MA and DFT-spread OFDM) and their corresponding applications in the LTE, WiMAX, WLAN and DVB-RCT standards are detailed. Capacity and flexibility enhancements of multi-carrier OFDM systems by different MIMO diversity techniques such as space time/frequency coding (STC, SFC) and software defined radio concepts are also described. Written in a highly accessible manner this book provides a unique reference on the topics of multi-carrier and spread spectrum communications, assisting 4G engineers with their implementation. Fully updated new edition of successful text, including two new chapters on LTE and WiMAX Describes in detail new applications of OFDM in mobile communication standards Examines all multi-carrier spread spectrum schemes, with in-depth analysis, from theory to practice Introduces the essentials of important wireless standards based on multi-carrier/spread spectrum techniques.

Download or read book Forward Error Correction Schemes for Data Communication Through Underwater Channel written by Dr. Raj Kumar Goswami and published by Horizon Books ( A Division of Ignited Minds Edutech P Ltd). This book was released on 2022-08-26 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary endeavor of this book is to provide an insight to the Forward Error Correction schemes so as to transfer the extracted features of the detected objects along with any intended data in a reliable manner through underwater channel. The main challenge with respect to the development of the coding techniques is the phenomena governing the propagation of signals through the underwater channel. It offers the biggest challenge imposing severe limitations on the effective throughput of transmission. The major problems encountered in the underwater channel are related to time-varying ISI and frequency-selective fading. An extensive literature review has also been presented with respect to Error Correction Coding schemes. This survey provided the necessary base for formulating the design alternatives. These alternatives attempted to exploit the recent advances in the error correction coding techniques, for data communication through underwater channel. Factors like design and implementation complexity of error correction schemes and the amount of overheads involved in transmission have also been considered in the critical assessment of these alternatives. An overview of the Sonar theory has also been presented along with the brief introduction of the forward-looking Sonars. The types of Forward-Looking Sonars have also been discussed in very brief. A comparison of the general parameters of the terrestrial and underwater systems is also carried out along with the variations in the path loss offered by the two systems with frequency and distance. The characteristics of propagation in the underwater medium are also elaborated. Underwater Channel modeling is also introduced in the book along with a study of the Rician and Rayleigh models which characterize the fading environment. The Rician and Rayleigh distributions are compared in terms of their application to real world scenarios. In the real underwater scenario, there is also a direct path along with the diffused/ indirect paths. Therefore, the most suitable model that can be used for testing the designed coding schemes is the Rician Fading model (K-factor = 2) along with the Additive White Gaussian Noise. The various Forward Error Correction Schemes have been discussed for the purpose of achieving reliable transmission of the formulated data block. The designs of the two Convolutional coding schemes i.e. rate 1/n and rate n/(n+1) have also been presented. It is observed from the comparison of Convolutional and TCM coding schemes that improvement in the performance of either code can be obtained with increase in the coding rate. The Turbo Codes have also been introduced and it will be seen that the performance of turbo code is sensitive to its code structure. The problem of the application of turbo codes to underwater communication systems has also been addressed. The main disadvantage of the Turbo codes is their long latency due to their relatively large codewords and iterative decoding process. However, the Turbo codes score over the Convolutional and the TCM codes in that they can be made sufficiently random to achieve a given BER and by using iterative methods, can be efficiently and feasibly decoded. The designed coding algorithm has been incorporated into the various configurations of the Turbo coding scheme. The variation in the configurations is in the coding rate and the number of states. The interleaver used in the design has been chosen as the random interleaver. The Turbo Coding Schemes have been designed by implementing the Convolutional coders as the constituent encoders using the proposed design rules. The design has been carried out for the 1/n and the n/(n+1) code rates with various states. The performance analysis of the proposed turbo schemes is also presented in terms of the Bit Error Rate (BER) achieved.

This book was released on 2012-12-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of first and second generation wireless systems has paved the way for further research opportunities towards the next generation systems. The two standards GSM and IS-95 based on TDMA and CDMA respectively, have deeply influenced our system-level understanding, bringing new perspectives on the problems associated with wireless networks and potential for innovations. This volume presents the proceedings of the second workshop on multiaccess, mobility and teletraffic for personal communications held in May 1996 in Paris, France where some important subjects on the next generation systems have been treated. These include topics dealing with information theoretic aspects, channel modeling, diversity, interference control, resource allocation, power control, packet multi-access, stochastic modeling of mobility and traffic, and wireless network control. The selected topics in this workshop and their presented set of solutions reflect the richness of the problems in wireless communications. Indeed, development of theoretical frameworks with considerable attention to the peculiar environment of wireless communications has been the prime objective of this workshop. To elaborate, consider the problem of multi-access methods which remains a challenge for researchers. A complete evaluation of an access scheme must consider different aspects such as propagation, interference, mobility and traffic modeling. Some common bases, paradigms and models are needed. For example, today, we do not have a common archetype like the A WGN channel as in classical statistical communication. Clearly, there is a need for justified assumptions and models.

Download or read book Multi-Carrier and Spread Spectrum Systems written by K. Fazel and published by John Wiley & Sons. This book was released on 2004-02-06 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frequency spectrum is a limited and valuable resource for wireless communications. A good example can be observed among network operators in Europe for the prices to pay for UMTS-frequency bands. Therefore, the first goal when designing future wireless communication systems (e.g. 4G - fourth generation) has to be the increase in spectral efficiency. The development in digital communications in the past years has enabled efficient modulation and coding techniques for robust and spectral efficient data, speech, audio and video transmission. These are the multi-carrier modulation (e.g. OFDM) and the spread spectrum technique (e.g. DS-CDMA), where OFDM was chosen for broadcast applications (DVB, DAB) as well as for broadband wireless indoor standards (ETSI HIPERLAN-II, IEEE-802.11) and the DS-CDMA was selected in mobile communications (IS-95, third generation mobile radio systems world wide, UMTS/IMT 2000). Since 1993 various combinations of multi-carrier (MC) modulation and the spread spectrum (SS) technique have been introduced and the field of MC-SS communications has become an independent and important research topic with increasing activities. New application fields have been proposed such as high rate cellular mobile, high rate wireless indoor and LMDS. It has been shown that MC-SS offers the high spectral efficiency, robustness and flexibility that is required for the next generation systems. Meanwhile, different alternative hybrid schemes such as OFDM/OFDMA, MC-TDMA, etc. have been deeply analysed and adopted in different international standards (ETSI-BRAN, IEEE-802 & MMAC). Multi-Carrier & Spread-Spectrum: Analysis of Hybrid Air Interfaces draws together all of the above mentioned hybrid schemes therefore providing a greatly needed resource for system engineers, telecommunication designers and researchers in order to enable them to develop, build and deploy several schemes based on MC-transmission for the next generation systems (which will be an integration of broadband multimedia services covering both 4G mobile and fixed wireless systems). * Offers a complete treatment of multi-carrier, spread-spectrum (SS) and time division multiplexing (TDM) techniques * Provides an in-depth insight into hybrid multiple access techniques based on multi-carrier (MC) transmission * Presents numerous hybrid multiple access and air interface architectures including OFDM/CDMA, MC-CDMA, MC-DS-CDMA and MT-CDMA * Covers new techniques such as space-time coding and software radio Telecommunications engineers, hardware & software system designers and researchers as well as students, lecturers and technicians will all find this an invaluable addition to their bookshelf.
