FEM-3

这是实现iir滤波器的matlab源代码，希望对用matlab设计滤波器的朋友有帮助！(This is the realization of iir filter matlab source code, want to design a filter with matlab friends help!)

with this package,we can perform pitch estimation with different techniques, which is valuable in speech analysis.

实现信号的SVD 分解,对信号中的奇异性进行监测，对突变信号点也可以很好监测(to complete the SVD for signals，Singularity of signal monitoring, signal monitoring point can be very good for mutations)

实现KALMAN滤波器设计,对刚刚开始现代数字信号处理的同胞们有借鉴作用(Kalman filter design to achieve the just the beginning of modern digital signal processing compatriots have reference)

一种经典MIMO信道模型的仿真程序，对于学习空时信道建模很有用(A classical MIMO channel model of simulation program for studying space-time channel modeling is useful)

说明：  非负矩阵分解nmf，通过迭代w和h，收敛后输出最终w和h。(Non-negative matrix decomposition nmf, through iteration W and h, the final W and H are output after convergence.)
