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.)

非线性动力系统中分叉图用来定性的表示系统行为的演化，本代码中ode1.m定义了一个经典的Lorenz系统，sode3.m对该系统计算并画出了参数敏感区的分叉图。(Nonlinear dynamic system bifurcation diagram used to express qualitative evolution of system behavior, the code defines a ode1.m classical Lorenz system, sode3.m of the system to calculate and draw the sensitive areas of the bifurcation parameter Fig.)

干扰可分为窄带和宽带，本程序主要针对宽带干扰信号进行编写(Interference can be divided into narrowband and broadband, the program is aimed at a broadband signal BPSK modulation )
