自己写的一个计算空间时频分布的程序，魏格纳威尔分布原代码(Wrote a frequency distribution calculating space program, Wigner distribution of the original code Weir)

用于对基于空间点的三维重建,非常好用,请多多指教,QQ:526289(for space-based point of the three-dimensional reconstruction, very handy, exhibitions, QQ : 526289)

在matlab中很适用，很经典的产生几种测试噪声的程序。(In matlab it is applicable, it is the classic noise generated several test procedures.)

利用matlab simulink 对某双闭环直流调速系统进行仿真(Simulation of Double closed loop dc speed control system with matlab simulink)

This code simulate, relay selection using the weak channel on ad-hoc and relay channels.Also power allocation is used for decrease consumed power.

通过piv速度计算溃坝过程的溃口流量，并输出结果(Calculation of dam breach flow process through piv speed and output)

说明：  这里实现的卷积码译码器可实现（n,1,K）的卷积译码，即一个输入码元，n个输出码元，编码器的约束长度为K，采用函数的默认值将实现（2,1,7）的卷积译码。译码方法为维特比硬判决译码，且译码开始状态假定为全零状态。(Here to realize convolutional code decoder can realize (n, 1, K) convolutional decoding, namely an input element, n output element, encoder constraint length is K, takes the default value of function, achieve the convolutional decoding,1,7 (2). Decoding method for decoding victor than hard decisions, and decoding the start state assumed to zero state.)
