A Cooperative and Alternate PTS Scheme for PAPR Reduction in STBC MIMO-OFDM System

摘要：

　　Multiple input multiple output orthogonal frequency division multiplexing (MIMO-OFDM) is an attractive transmission technique for high-bit-rate communication systems.Like OFDM,one main disadvantage of MIMO-OFDM is the high peak-to-average power ratio (PAPR) of the transmitters output signal on different antennas.The partial transmit sequences (PTS) approach provides optimal performance for PAPR reduction.However the computational complexity of traditional PTS method is tremendous.In this paper,a cooperative and alternate PTS (C-A-PTS) scheme for STBC MIMO-OFDM system is proposed which can achieve nearly optimum PAPR performance at much less complexity.The simulation results prove the effectiveness of the advanced algorithm.
