CONVERT A MATRIX TO LOWER TRIANGULAR MATRIX

说明：  利用伪随机序列作为发送信号，经过信道，产生了频偏和相位偏移，利用数字锁相环的原理实现对信号的频率估计和相位估计，实现信号的载波同步。(The frequency offset and phase offset are generated by using pseudo-random sequence as the transmitting signal through the channel. The frequency estimation and phase estimation of the signal are realized by using the principle of digital phase-locked loop, and the carrier synchronization of the signal is realized.)

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.
