高斯白噪声的两种MATLAB实现方式，可以用，已经试验了(AWGN)

伪魏格勒分布源代码.适合于非稳态的时频联合分析,可直接用于MATLAB编程,无解压密码.(pseudo-source code distribution. Suited to the non-steady-state joint time-frequency analysis can be used directly in MATLAB programming, without extracting passwords.)

本程序仿真了AWGN信道下，采用DS扩频对bpsk信号的影响，扩频码采用walsh码，扩频因子16； 接收端进行rake接收，然后分集合并，比较了三种分集方式对误码率的影响 从图像可以看出在扩频因子较高的情况下，最大比值合并与等增益合并性能相近(This program simulates the AWGN channel, using DS spread spectrum signal for bpsk influence spreading code using walsh code spreading factor 16 Rake receiver receiving end, and diversity combining, diversity compares three methods on the bit error rate of As can be seen from the image in the case of higher spreading factor, the maximum ratio combining and equal gain combining similar performance)

Code contains MATLAB code of Spectrum Subtraction algorithm for reducing noise from noisy speech signal.
