doi:10.3969/j.issn.1000-1093.2020.06.011

Abstract

Abstract: The orthogonal frequency division multiplexing (OFDM) is widely used in wireless system and becoming a key technology for weapon cooperation data link. A hybrid peak average power ratio (PAPR) reduction algorithm is proposed. It is based on modified partial transmission sequence (PTS) and compressed sensing (CS) in OFDM for further reducing PAPR and improving bit error rate performance. The framework and implementation steps of the algorithm are also proposed, which includes PAPR reduction at transmitter and CS recovery at receiver. Simulated results show that the algorithm combines the advantages of CS and PTS, reducing the peak-average power ratio by at least 1dB, and achieving better PAPR performance. Key

Key words: orthogonalfrequencydivisionmultiplexing, peakaveragepowerratio, partialtransmissionsequence, compressedsensing
