Abstract :
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 transmitter´s 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.
