说明：In this paper, we present a Selected Mapping (SLM) PAPR reduction technique for MIMOOFDM system with special protection of Side Information (SI). Selected Mapping (SLM) is a powerful PAPR reduction technique since it does not cause any signal distortion and simple to implement. As a special protection for the Side Information (SI) of SLM technique, we propose a SI power allocation procedure. Simulation results show that our proposed technique gives significantly better BER performance than the ordinary SLM technique for MIMO-OFDM systems. Analysis for the optimum SI power allocation is also presented.

说明：Selective mapping algorithm is proposed to reduce the peak-to-average power ration (PAPR) in MIMO-OFDM system. It is proved that the conjugate symbols on two antennas have the same PAPR property with orthogonal space-time block coded (STBC). By using the characteristic, the computational complexity cost and the side information (SI) is significantly reduced compared with the concurrent SLM algorithm. Simulation results demonstrate that the performance of the proposed algorithm outperforms the conventional concurrent SLM algorithm.

The parameters of the simulation are determined by standard IEEE 802.11n. From the simulation results, it is shown the proposed method has better PAPR performance in this system. Additionally, when the number of sub-blocks is increased, high PAPR reduction performance can be obtained.

说明：The DSI method is basically a modified SLM method. The additional aspect of the DSI method is to add M-bits dummy sequences to the original sequence in order to reduce the PAPR. Where, the dummy bits are inserted at the end of the data sequence (y). Next, after IFFT, we select the M-DSI sequence having the lowest PAPR.
