Abstract

The major drawback of multicarrier transmission such as Orthogonal Frequency Division Multiplexing (OFDM) and Wavelet Packet Modulation (WPM) is their high Peak-to-Average Power Ratio (PAPR). In this paper, we propose Genetic Algorithm (GA) based approach for the reduction of PAPR. The GA approach has proved to be an efficient optimization tool for the reduction of PAPR as well as the computational load. The results show that the P APR of the original WPM signal is 12.5 dB and that obtained after applying GA is 9.5 dB, thereby reducing the PAPR by about 3dB. Further, it is observed that GA performs better than Partial Transmit Sequence (PTS) and Selective Mapping Technique (SLM) if number of generations is increased.
