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.

Download or read book Papr Reduction Techniques in Wireless Ofdma Networks written by Kamal Singh Rana and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, some of the existing PAPR reduction techniques have been analyzed. After discussing the existing PAPR reduction techniques, two new PAPR reduction techniques have been proposed which are based on the existing schemes. The simulation results for the proposed techniques are compared with some of the existing techniques like, Partial Transmit Sequences (PTS), Selective Mapping (SLM), Iterative flipping and new SLM. Although all the existing techniques can reduce the Peak to Average Power Ratio (PAPR), the computer simulation results show that the Proposed techniques can offer better Peak to Average Power Ratio (PAPR) reduction performance. These proposed techniques have been named as Proposed Technique1 and Proposed Technique2 in this work. The results also show that the Proposed technique2 performs better than Proposed technique1 in terms of PAPR reduction when the numbers of subblocks in the OFDM transmitted signal increases. However, when the number of sub-blocks is comparatively lesser, the proposed technique1 gives better performance. The PAPR reduction performance analysis of the existing and proposed techniques is the main focus of my paper.

Available in PDF, EPUB and Kindle. Book excerpt: ... In this thesis, two schemes are proposed for joint reduction of PICR and PAPR. Simulation results are presented to demonstrate efficacy of the proposed schemes in reducing PAPR and PICR. The low computational complexity makes them appropriate for practical OFDM systems. In addition, the joint PAPR, PICR, and OBP design problem is also considered in this thesis. Two approaches, the phase rotation approach and the constellation extension approach, are proposed for this joint design problem. In each approach, this joint problem is modelled as a constrained optimization problem with continuous variables. The optimization problem is then relaxed into a second order cone programming (SOCP) problem, whose global optimal solution can be obtained efficiently. Simulation results show that the proposed schemes are effective and the optimized OFDM system has very good performance."--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: Many techniques have been applied for peak-to-average power ratio (PPAPR) reduction. The use of peak reduction carrier (PRC) scheme proposed by Lawrey and Kikkert (1999) for PAPR reduction is further investigated in this research work for the PRCs search complexity of the algorithm. A new mathematical formulation and the integration of suitable components for SA have been found for the optimum algorithm. As a result, a more efficient SA based algorithm was found with less processing time required for PAPR reduction.

Download or read book Enhanced Peak to Average Power Ratio (PAPR) Algorithm in Long Term Evolution (LTE) Standard written by Mohanad Janat and published by . This book was released on 2014 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long Term Evolution (LTE), is an OFDM based system considered the 4G standard that supports high mobility up to 350km/h and high bandwidths. However, LTE suffers from high peak to average power ratio (PAPR) which critically affects the system performance by increasing the bit error rate and decreasing the spectral efficiency. Many solutions have been introduced to the LTE standard to overcome this issue. A hardware solution has been suggested utilizes high power amplifiers with very wide linearity area covering the high peak area of the OFDM symbol, but, the solution is expensive rendering it not affordable by end users. Thus, PAPR reduction algorithms come into place to resolve the issue by manipulating the OFDM symbols blocks produced by MIMO-OFDM systems. The result is an increase in the efficiency of the whole system by reducing PAPR. However, a lot of these algorithms suffer increasing computational complexity to achieve high PAPR reduction performance which affects the overall circuitry complexity. A modified algorithm has been proposed in this research that aims to achieve high PAPR reduction performance while keeping the computational complexity level as low as possible. A modified Cross Antenna Rotation and Inversion (CARI) is introduced in this work, where the normal CARI operations are applied to the first two blocks in the space domain which maintains the circuitry complexity lower than the original CARI, followed by a rotation in the space and frequency domains, hence, utilizing the degree of freedom inherent in both OFDM-MIMO space and frequency domains. The proposed PAPR reduction scheme has been evaluated using Matlab simulator. For simulation approach, the performance metric considered is the Complementary Cumulative Distribution Function CCDF averaged our 105 OFDM symbols. The results have shown that the proposed scheme has better performance by gain of 0.18dB than original CARI at CCDF=10-3 and the sub-blocks M=8. The bench marking against Individual SLM the proposed scheme has shown better performance by gain of 0.5dB than Individual SLM at CCDF=10-3 and the sub-blocks M=8, and finally with concurrent SLM the proposed scheme has better performance by gain of 0.8dB Individual SLM at CCDF=10-3 and the sub-blocks M=8.
