这是本论文的仿真部分，是对MIMO系统理论的验证。本论文将分别从两种情况来对系统进行仿真：不同的信噪比下，发射天线数 为4，接收天线 逐渐增大；不同的信噪比下，接收天线 为4，发射天线数 逐渐增大。然后分别绘出他们的仿真图，并对它进行分析(This is the simulation part of this paper is to verify the theory of MIMO systems. In this paper, two cases will come from the system simulation: different signal to noise ratio, the number of transmission antennas is 4, the receiving antenna is gradually increasing different signal to noise ratio, the receiving antenna 4, gradually increasing the number of transmission antennas Great. And then mapped to their respective simulation map, and analyze it)

1、本程序用于仿真里德-穆勒（Reed-Muller）码在AWGN信道中的性能，调制采用bpsk 2、理论请参见《差错控制编码》（第二版），Shu Lin（美）编，晏坚等（译）一书P70-75.且仿真结果与书中图4-2完全一致 3、BPSK_AWGN_RM_Code.m为主程序，点击运行即可 4、The_creation_of_RM_code.m和RM_Decode.m分别为RM码的编、译码程序，而Majority_logic_decision.m用于译码中的大数判决，combine_dunction.m用于计算组合数。(1, the procedure for the simulation Reed- Muller (Reed-Muller) codes in AWGN channel performance, modulation using bpsk 2, theory, see " Error Control Coding" (second edition), Shu Lin (America) series , Yan Jian, etc. (translated) book P70-75., and the simulation results consistent with the book Figure 4-2 3, BPSK_AWGN_RM_Code.m-based program, click Run to 4, The_creation_of_RM_code.m and RM_Decode.m were RM compiled code decoding process, and in large numbers for decoding Majority_logic_decision.m judgment, combine_dunction.m used to calculate the number of combinations.)
