IIR平滑器的作用和特点演示，包括b取何值时，信号部分通过系统后不变？噪声部分是否放大了？计算NRR和系统频响 (IIR smoother presentation of the role and characteristics, including the b take what value, the signal in part through the system after the change? Whether the part of amplified noise? NRR and system frequency response calculation)

小波的源代码。有关MATLAB的共同学习吧(wavelet source. The MATLAB common learning it)

c++ 通用弹道仿真计算程序(经典版) 程序源代码(c++ common trajectory simulation program (classic version) source code)

this is basic matlab explanation. i will upload 5documents.

有两个程序一个是关于frft的源程序，一个是应用frft对线性调频信号进行检测的程序，原理是以变换阶数（不同的分数阶域）为变量对观测信号进行分数阶变换，形成信号能量在时频平面上的二维分布，在此平面上按阈值进行峰值点的二维搜索即可检测线性调频信号并估计其参数。(There are two procedures one on frft the source, one application frft linear FM signal detection process, the principle is to transform the order of (different fractional domain) as the independent variables on the observed fractional signal change, the formation of signal energy in two-dimensional time-frequency plane distribution in this plane, the peak threshold value by two-dimensional linear FM signal can be detected search and estimate its parameters.)

说明：  程序实现了匈牙利算法应用于指派问题，输入指派成本矩阵C，给出最小成本及使得成本最小的最优指派(Input the assignment cost matrix C, the program will obtain the least cost and the optimal assignment vector.)

卷积码是一种有记忆的编码，这里提供了卷积码的维特比译码函数(convolutional code is a kind of code memory, it provides Convolutional Codes Viterbi decoding function)
