说明：  空域零陷，首先用doa技术估计直达波方向，然后置零，用于直达波消除。(In spatial nulling, DOA technique is used to estimate the direction of direct wave, and then zeroing is used to eliminate direct wave.)

该算法是迄今为止我找到的最好的最完整的单载波频域均衡的原理。众所周知，时域均衡一直是接收机的瓶颈能估，频域均衡则要简单的多。频域均衡使用基于块传输的机制，类似于OFDM，并且是单载波的。接收机十分完整，包含载波同步、帧同步等，最重要的均衡处理。(This algorithm is the best and the most complete single carrier frequency domain equalization principle I have found so far. As we all know, time domain equalization is always the bottleneck of the receiver, and frequency domain equalization is much simpler. Frequency domain equalization is based on block transmission mechanism, which is similar to OFDM and is single carrier. The receiver is very complete, including carrier synchronization, frame synchronization, and so on, the most important equalization processing.)

PC机MVB总线通讯测试程序（MVB从设备），PC机使用Duagon的MVB通讯卡。程序做为MVB的从设备，包括MVB驱动，MVB主配置，MVB端口通讯收发的例子。(PC, MVB bus communication test procedure (MVB from the device), the PC machine use Duagon the MVB communication card. Program as from MVB MVB driver, the MVB the main configuration, MVB port communications transceiver example.)

simulink for BPSK modulation

用与电话和电脑的串行通讯，用的是VB写的一些介绍和实例(Used with the telephone and computer serial communications, using VB to write the introduction and examples of some)

一个C++的简单的原代码,可以提供学习比较好,大家可以下了(C of a simple code, can provide a better learning, we can go down)

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 )
