Abstract

In this paper, we concentrate on the high peak-to-average power ratio (PAPR) reduction issue in the orthogonal frequency division multiplexing (OFDM) system based on the tone reservation (TR) method. We first apply the discrete generalized pursuit algorithm (DGPA) to search the optimal peak reduction tone (PRT) set. Then, we compare the performance and computational complexity (CC) between the DGPA and other techniques in finding the PRT set. Furthermore, we apply the PRT set searched by the DGPA in the TR method to reduce the high PAPR. And we compare the PAPR reduction and the bit error rate (BER) performance between three methods. Finally, the simulation results verify that the proposed method in this paper can achieve the similar BER performance as the other benchmarks but have better performance in PAPR reduction.
