PTS algorithm for PAPR suppression of WOFDM system

Abstract

Partial transmit sequence is an efficient algorithm to solve the problem of high peak-to-average power ratio (P APR) in orthogonal frequency division multiplexing (OFDM).In this paper the PTS algorithm is used in Wavelet Packet Based Multi-Carrier Modulation system, but it still requires high computational complexity. A sUb-optimum PTS algorithm based on combined random-interleaved partition and Hadamard matrix is proposed to solve this problem. Simulation shows that the improved algorithm proposed in this paper can achieve good P APR reduction with low computational complexity and have nearly no influence on the bit error rate performance.
