说明：  用窗函数法设计一个能对模拟信号进行滤波的线性相位FIR低通滤波器。抽样频率为 kHz，通带截止频率为 kHz，阻带截止频率为 kHz，要求阻带最小衰减 dB。为了降低运算量，所设计滤波器的阶数要尽可能的低(With the window method to design a filter to the analog signals of linear phase FIR low-pass filter. Sampling frequency is kHz, passband cutoff frequency kHz, stopband cutoff frequency of kHz, the minimum required stopband attenuation dB. To reduce the computation, the order of the filter designed to be as low as possible)

多序列跳频系统及其在AWGN信道下误码率性能分析(Multiple sequence and frequency hopping system BER performance analysis in AWGN channel)

说明：  用matlab编的语音增强的一个程序，是用维纳滤波实现的，(Matlab made use of a speech enhancement procedure, Wiener filter is used to achieve,)

说明：  这是信道估计在matlab的详尽实现，已经调试成功，可以实现(Channel estimation in matlab detailed implementation, debugging has been successful, and can achieve)

CFAR一种门限设定方法，可以很好地对波动大的区域进行门限设定(CFAR of a threshold setting method, can be a good area for large fluctuations in the threshold setting)
