This book was released on 2011-02 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Orthogonal Frequency Division Multiplexing (OFDM) techniques allow the transmission of high data rates over broadband radio channels subject to multipath fading without the need for powerful channel equalization. However, they are very sensitive to nonlinear effects owing to high peak-to-average power ratio (PAPR) owned by their transmitted signals. This thesis proposes an efficient technique for reducing the PAPR of OFDM signals.The proposed technique is data-independent and, thus, does not require new processing and optimization for each transmitted OFDM block. The reduction in PAPR of the OFDM signal is obtained through a proper selection of a pulse shaping scheme that distributes the power of each modulated symbol over the OFDM block such that the average power of OFDM signal will not be far from individual symbol power. It is shown, through computer simulations, that the PAPR of pulse shaped OFDM signals approaches that of single-carrier signals.The pulse shaping schemes also take advantage of the frequency variations of the communication channel and can provide considerable performance gain in multipath fading channels
Book Synopsis PAPR Reduction of OFDM Signals Using Pulse Shaping by : Yuwen Jian

Available in PDF, EPUB and Kindle. Book excerpt: In this thesis an approach to generate the optimal pulse shaping matrix is proposed to minimize the signal distortions while keeping the PAPR reduction ability for this pulse shaping method. Numerical study has proved the PAPR reduction ability for the pulse shaping scheme. However, it is not desirable to obtain the CCDF through simulation due to its inefficiency. Thus, theoretical study is needed to analyze the PAPR for OFDM with pulse shaping. In the literature the analysis of PAPR distribution is based on the OFDM signal without pulse shaping being stationary. In this thesis, a proper transformation is applied to transform the non-stationary OFDM signal with pulse shaping into a stationary signal and the PAPR distribution is analyzed. Due to the difficulty representing PAPR distribution in close form, an upper bound for the CCDF of PAPR will be derived instead for OFDM signals with suitably choosing pulse shaping filters. Numerical study has also been carried out to test and verify our theoretical analysis results.

Book excerpt: Communication is one of the important aspects of life. With the advancement in age and its growing demands, there has been rapid growth in the field of communications. Signals, which were initially sent in the analog domain, are being sent more and more in the digital domain these days. For better transmission, even single - carrier waves are being replaced by multi - carriers. Multi - carrier systems like CDMA and OFDM are now - a - days being implemented commonly. In the OFDM system, orthogonally placed sub - carriers are used to carry the data from the transmitter end to the receiver end. Presence of guard band in this system deals with the problem of ISI and noise is minimized by larger number of sub - carriers. But the large Peak - to - Average Power Ratio of these signal have some undesirable effects on the system. In this thesis we have focused on learning the basics of an OFDM System and have undertaken various methods to reduce the PAPR in the system so that this system can be used more commonly and effectively.
