Abstract

Orthogonal frequency division multiplexing (OFDM) has gained a much attention for wireless communication technology in recent years. OFDM signal has a large peak-to-average power ratio (PAPR), which brings disadvantages like a degradation of the BER performance and the radiation of the out-of-hand spectrum. To reduce the large PAPR, using complementary sequences as input to generate an OFDM symbol is one of effective techniques. A coding scheme of complementary sequences taking the advantage of the code redundancy in nonlinear OFDM systems is proposed, and computer simulation has been preformed. The results show that the out-of-band spectrum is suppressed and the BER performance is also improved compared with uncoded signal, using complementary sequences is an effective method for spectrum suppression and BER improvement in nonlinear OFDM systems.
