Abstract

This paper describes a new PAPR (peak to average power ratio) reduction approach in MC-CDMA (multicarrier code division multiple access) system (in so called M-modification). The spreading sequence introduces coherence among subcarriers. This is used for chip position formatting to PAPR minimization. The optimizations methods are used to get best chip interleaving sequence (namely genetic algorithm (GA) and ant colony optimization (ACO)). BER simulation in AWGN (additive white Gaussian noise) channel with clipping is presented to evaluate efficiency of this concept
