matlaab code ffor basic OFDM

说明：  冈萨雷斯教材中的源代码，以及一些matlab源程序(Gonzalez materials of the source code, as well as some source code matlab)

matlab低通滤波器，初学，简单程序(err)

matlab的gui设计程序,有关<信号与系统>课程的辅助教学设计(Matlab gui design procedures, the)

参数辨识问题，本程序是基于RLS法的参数辨识最新解法(Based on the RLS parameter identification)

基于MATLAB平台的ofdm的无线信道算法，包括BER等(MATLAB-based platform of the wireless channel OFDM algorithm, including the BER, etc.)

MIMO与LDPC结合，很好的代码，其中是用QCLDPC码，(MIMO and LDPC combination of good code, which QCLDPC code )

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.)
