产生两个均值为m,方差为sgma的高斯随机变量，当输入参数只有一个时，认为均值为0。(mean to have two m, sgma variance for the Gaussian random variables, when only one input parameters, that the mean of 0.)

说明：  都是关于空间普估计算法，其中有解相干和非相干算法以及它们之间的对比( the spatial spectrum estimation)

ofdm signal without noise

利用模拟退火算法求解已知函数的最小值，即模拟退火算法寻优问题，可以广泛推广。(Using simulated annealing algorithm to solve the minimum of the known function, that is, the simulated annealing algorithm optimization problem, can be widely promoted.)

Solves part b for three values of p: 0.1, 0.3, 0.5, and 0.8. To solve for other values of p, just change the numbers in the vector p below.

4. 数字信道化抗干扰反正，首先数字信道化多相滤波，差值的倍数为信道数的两倍，再采用AGC技术抗干扰。(4 digital channel anti-jamming anyway, the first digital channel of the polyphase filter, the difference in multiples of twice the number of channels, and then using the AGC technology anti-jamming.)

说明：  这里面包含两个程序段，是学习SIMULINK的基础程序，很有借鉴意义，不学习的就不要浪费时间了(This procedure consists of two paragraphs which is the basis of SIMULINK learning process, referential significance, not to learn not to waste time on)

小波包分析提取振动信号中的特征频率，真的是一个好程序，窗函数法设计一个数字带通FIR滤波器。( Wavelet packet analysis to extract vibration signal characteristic frequency, Really is a good program, A window function design FIR digital band-pass filter.)
