A Hybrid PAPR Reduction Scheme Using Selective Mapping and Amplitude Clipping
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2015, Vol 2, Issue 3
Abstract
High information rate is the major requirement of modern communication systems. As there is the scarcity of spectrum OFDM proves itself very useful. In OFDM the subcarriers are made adjacent and orthogonal to each other so as to avoid interference. To increase the data rate number of subcarrier has to be increased which results in the noteworthy issue of high PAPR. The main reason for high PAPR is high peak values of subcarriers than the average value. The Hybrid scheme is introduced for PAPR lessening in this paper.
