A novel method in SLM to produce m sequence to reduce the PAPR in MIMO-OFDM system

Compared with other multi carrier modulate systems, MIMO-OFDM also adopting this kind of technique, is prone to produce high peak-to-average power ratio (PAPR), which will result in frequency spectrum spread and in-band distortion enormously due to the nonlinearity of the high power amplifier. To this main fault in MIMO-OFDM, many scholars propose some new idea to overcome it. Based on SLM technique, this paper mainly resorts to the copy theory to produce the m sequence for the sake of optimize the revolving vector, which decreases the probability of high PAPR more efficiently.
