该程序提供V-BLAST MIMO系统检测算法相关程序，可采用不同的调制方式，检测算法包括ZF、MMWE、ML及串行干扰抵消检测算法程序。初学者使用很好的程序。(The program provides V-BLAST MIMO detection algorithm system procedures, can be a different modulation, detection algorithms, including ZF, MMWE, ML, and serial interference cancellation detection algorithm. Use a good program for beginners.)

说明：  语言的文法规则 说明 对原编译程序作了如下修改,增加了输入文件(The grammar rules of the language have been modified as follows to add input files to the original compile)

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 )

modbus library written in c sharp!!!!!

说明：  通过matlab来实现带通滤波，可自由设置带通范围，滤波效率高，结果精确(Through MATLAB to achieve band-pass filtering, the band-pass range can be set freely, the filtering efficiency is high and the result is accurate)
