MIMO_Capacity
MIMO指多输入多输出，MIMO技术大致可以分为两类：发射/接收分集和空间复用。传统的多天线被用来增加分集度从而克服信道衰落，具有相同信息的信号通过不同的路径被发送出去，在接收机端可以获得数据符号多个独立衰落的复制品，从而获得更高的接收可靠性。这种技术往往要结合多天线技术，而多天线技术在移动通信中得到了广泛的研究。(MIMO refers to Multiple Input Multiple Output, MIMO technology can be broadly classified into two categories: transmit/receive diversity and spatial multiplexing. Traditional multi-antenna was used to increase the degree of diversity to overcome channel fading, the signal with the same information through different paths have been sent in the receiver-side data symbols can be multiple independent copies of the decline, which was higher reception reliability. This technology often have to combine multi-antenna technology, and multi-antenna technology in mobile communication has been widely studied.)

程序
说明： 1、基带码型仿真
（1）通过仿真观察占空比为50%、 75%以及100%的单、
双极性归零码波形以及其功率谱，分析不同占空比对
仿真结果的影响。
（2） 通过仿真产生一随机消息码序列，将其分别转换为
AMI码和HDB3码，观察它们的波形及其功率谱密度。
2、数字带通调制系统仿真
设计一个采用2ASK（ OOK） 调制的数字通信系统：
产生二进制随机数据，并仿真其对应的2ASK调制波形，
分析其频谱。所产生的调制波形加入不同信噪比的白噪声，
选取合适的接收方案，画出系统误码率曲线，并与理论误
码率进行对比。(1.Baseband pattern simulation

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.
