说明：  OFDM计算，调制方式为64QAM，可以对信道的信息进行估计(OFDM calculation, modulation mode is 64QAM, can estimate the channel information)

说明：  C语言 注释清晰 可运行 BM算法编码译码 BCH(C BM encode decode BCH)

高通平台电信版CDMA手机写入MEID号码(Write MEID tool for Qualcomm platfrom)

扩频通信系统实用仿真技术一书的所有源代码,包括 信道编码译码(有LDPC码),扩频调制,载波调制,PN码同步,窄带干扰抑制,直扩频系统仿真实列,跳频系统仿真实例等(spread spectrum system simulate technology)

空时编码，内容涉及mImo的各个方面，介绍很全面，很有帮助(Space-time coding, covering all aspects of Mimo, introduce very comprehensive, very helpful)

a file for digital modulation

LFM信号及回波的生成，时域及频谱分析，模糊度函数分析，时频分析，匹配滤波器能量检测、循环相关检测、及fmusic参数估计(LFM signal and the echo generation, time domain and spectral analysis, ambiguity function analysis, time-frequency analysis, the matched filter energy detection, loop correlation detection, parameter estimation and fmusic)

说明：  实现了一个直接扩频系统，使用BPSK作为调制解调方法。并比较白噪声AWGN及瑞利衰落(rayleigh fading)环境下，误码率的影响。(There are two files in the zip folder. bpsk_spread.m and jakesmodel.m Steps for simulation: 1] Run jakesmodel.m first 2] Then run bpsk_spread.m . 3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented 4] The resulting performance is stored in BER_awgn. 5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file. 6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable. 7] Run the simulation. To compare the perfromances of the receiver using DSSS plot the BER_awgn and BER_ray >>semilogy([1:8],BER_awgn(1:8), g* ) hold on semilogy([1:8],BER_ray(1:8), -.b* ) hold on grid on )

实现了LDPC码的编码 LDPC译码、LDPC校验矩阵的生成等。是完整的LDPC代码。测试了，跑的通。自学LDPC码的资料(Implements the LDPC encoding of LDPC decoding, LDPC check matrix generation and so on. LDPC code is complete. Tested and run through. Self-study of LDPC codes)

用于labview 串口通讯,非常有用，并且实测有用(useing for labview serial communicaton,it very useful)
