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：  对当前通信信号中常用的数字调相信号BPSK、QPSK、1／4一QPSK、8PSK的调制识别问题，提出了一种基于信号差分高阶累积量的识剐算法。该算法分两个层次进行调制识别，首先利用信号的四阶累积量特征对BPSK、QPSK和{1／4一QPSK、8PSK}信号进行识别，然后再利用信号差分的四阶和八阶累积量特征对1/4-QPSK、8PSK信号进行识别。从理论上分析了的该算法的有效性，并通过计算机仿真验证了算法具有良好的性能。(A recognition algorithm based on differential high-order cumulant is proposed for the modulation recognition problems of BPSK, QPSK, 1/4-QPSK and 8PSK, which are commonly used in current communication signals. The algorithm is divided into two levels for modulation recognition. Firstly, BPSK, QPSK and {1/4-QPSK, 8PSK} signals are identified by using the fourth-order cumulant characteristics of signals, and then 1/4-QPSK and 8PSK signals are identified by using the fourth-order cumulant and eighth-order cumulant characteristics of signal difference. The validity of the algorithm is analyzed theoretically, and the good performance of the algorithm is verified by computer simulation.)
