Description: 在linux平台下,纯c写的盲信号分离的代码.它采用基于卷积混合的盲信号分离算法,不但可以分离人工合成的混合信号,而且对于真实环境中的卷积混合的语音信号也能够分离.在本程序中,包含了两个测试文件,makefile后便可以直接使用.
另外值得一提的是,压缩包里包含有一些语音处理方面的常用函数.例如fft变换,读取\\写入wav文件,以及一些常用的一维向量和二维矩阵变换的函数.这些可以直接应用在其他应用程序里去.-in linux platform, net write c Blind Signal Separation code. it is based on convolution of mixed Blind Signal Separation algorithm, not only can be separated from the artificial synthesis of mixed-signal, but for the real environment convolution of mixed voice signals can be separated. in this procedure, the tests included two documents, makefile can be used directly after. Also worth mentioning is that Compression bag containing some of voice processing functions commonly used. fft transform, for example, to read \\ write wav file, and some of the commonly used one-dimensional and two-dimensional vector matrix transformation functions. these can be directly applied to other applications going.

Description: The code performs a number (ITERS) of iterations of the
Bailey s 6-step FFT algorithm (following the ideas in the
CMU Task parallel suite).
1.- Generates an input signal vector (dgen) with size
n=n1xn2 stored in row major order
In this code the size of the input signal
is NN=NxN (n=NN, n1=n2=N)
2.- Transpose (tpose) A to have it stored in column
major order
3.- Perform independent FFTs on the rows (cffts)
4.- Scale each element of the resulting array by a
factor of w[n]**(p*q)
5.- Transpose (tpose) to prepair it for the next step
6.- Perform independent FFTs on the rows (cffts)
7.- Transpose the resulting matrix
The code requires nested Parallelism.-The code performs a number (ITERS) of iterations of the

Description: 互相关模糊函数的matlab程序，很不错的，- cross_ambfn2.m- amodification of "ambfn1.m" for plotting cross ambiguity
between two signals OF THE SAME LENGTH
Designed to allow mismatch caused by FFT Doppler processing a pulse train.
The two signals differ only in phases (if there is
frequency mode it is the same in both signals.
ambfn1.m- plots ambiguity function of a signal u_basic (row vector)
The m-file returns a plot of quadrants 1 and 2 of the ambiguity function of a signal
The ambiguity function is defined as:
