Interleaving Optimization in OFDM PAPR Reduction

Abstract

One of approaches in the Peak to Average Power Ratio (PAPR) reduction methods for Orthogonal Frequency Division Multiplex (OFDM) is multiple signal representation (MSR) technique. This article presents the improvement of MSR technique where multiple signal representations are produced by different interleavers. The interleavers used in this approach are optimized and integrated with phase rotation (realized as element-by-element multiplying). The simulation for two-branch classical and optimized MSR is introduced in the article. The improvement in complementary cumulative distribution function of(CCDF) PAPR is presented.
