WebSep 6, 2014 · Orthogonal frequency division multiplexing (OFDM) is a common technique in multi carrier communications. One of the major issues in developing OFDM is the high peak to average power ratio (PAPR). Golay sequences have been introduced to construct 64-quaternary amplitude modulation (QAM) code for the OFDM, reducing the peak-to-mean … WebSep 22, 2024 · peak to average power ratio.
