Abstract: According to complementary sequence characteristics, we study the algorithm for PAPR reduction in OFDM systems
with Golay complementary sequences which are constructed by the Reed-Muller codes. In terms of the balance between complexity
and implementation, we propose a new decoding scheme, which makes selection in the cosets so as to reduce the complexity of
decoding and satisfy the real-time requirement. Finally, the simulation results in the AWGN channels show that the proposed
algorithm can constrain PAPR within 6 dB and achieves satisfactory BER performance.

Key words: orthogonal frequency division multiplexing(OFDM), peak to average power ratio(PAPR), complementary sequences, Reed-Muller code(RM)
