求出信号噪声的方差，对干扰信号的噪声的方差进行估测。( EVAR Noise variance estimation. Assuming that the deterministic function Y has additive Gaussian noise, EVAR(Y) returns an estimated variance of this noise.)

overall snr estimation in signal

基于正交基的信道估计，用于高速移动系统的信道估计(Orthogonal basis based channel estimation for high-speed mobile system channel estimation)

说明：  滑模变控制趋近律控制程序(Sliding mode variable control reaching law control program)

对给定集合A和B，能够编出求A和B的并集C的程序。(For a given set A and B, can be compiled out of order to A and B, and the set of C procedures.)

此为基于二代提升小波的阈值压缩算法源码，其中可以设置小波变换的分解层数，使用的小波名称，及各层阈值设置计算公式中的参数。并将低频系数转化为十六进制，方便在其上进一步压缩，如采用Huffman压缩等，程序思路清楚，附有完整的注释，可以使用多种小波，并且很好得体现了二代小波的思想，对于初学小波者帮助很大。(。-based on the second generation of this upgrade wavelet compression algorithm threshold source, which can set wavelet transform decomposition level, the use of wavelet name, threshold levels and set the formula for calculating the parameters. And low-frequency coefficients into hexadecimal facilitate its further compression, such as the Huffman compression. procedures ideas clearly, with the integrity of the Notes, you can use a variety of wavelet, and reflected very well in the second generation wavelet thinking, For beginners who wavelet of great help. )
