mimo_ofdm_slm
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.

MIMOOFDMPrecoding
TD-LTE下行传输采用了MIMO-OFDM的物理层构架，通过最多4个发射天线并行传输多个（最多4个）数据流，能够有效地提高峰值传输速率。LTE的物理层处理过程中，预编码是其核心功能模块，物理下行共享信道的几种主要传输模式都是通过预编码实现的。(The td-scdma LTE downlink transmission adopted MIMO - OFDM frame, the physical transmission antennas parallel transmission by up to four more (up to 4) data flow, can effectively improve the peak transmission rate.LTE) in the process of the physical layer of precoding is its core function module, several kinds of main physical downlink Shared channel transmission model is achieved by precoding.)
