hi Jkormanski,

i wanted to know how can we modify your code to perform demixing of 3 or 4 signals

Re: cocktail party problem matlab code

Hello as_518 ,you can download "handbook of neural networks signal processing"+matlab files from here:

**broken link removed**

this file no longer exists in rapidshare. i need the matlab files urgently cuz we are unable to figure out how to implement ica. plz mail the prg to nacharya017@gmail.com
i need to separate a mixture of two voice signals using ICA. plz help. its urgent

Re: single blind signal separation matlab

I am working on Speech processing and my topic is Speaker Verification. I have to also seperate two voice signals which are mixed together. If possible help me and provide matlab code that you have generated.

Re: signal seperation by matlab

I had a look into the methods of Independent Component Analysis.. looked intresting.. came across couple of books (one posted in this site).. Are you just trying to formulate new algorithms or trying to modify the method of ICA ?

i doing my project in speech signals to separate the mixed audiosignals
using ICA algorithm
i need the ICA algorithm for , (matlab code ) please forward this mail id
smallking11@ymail.com
please please very urgent.....

Re: cocktail party problem bss

All the discussion taking place here is about a mixture of linear processes....could someone tell me if there is any way to get arround the problem of blind source separation of volterra outputs with the use of Higher Order Statistics only.

Hi Mileoung,
checkthis out . it is about kurstosis(4th order statistics) maximization for BSS

Hi everybody,
I am doing my final year project regarding Identify Musical Instruments. I am trying to do this using wavelets. But I don't have enough knowledge in matlab programming and wavelets. If anybody know have idea about this project please help.

sorry for my english.

Re: blind signal separation matlab

Hello, i uploaded my m-files + 2 wav files with voices,the code isnt so complicated and i added some comments.To run it just type bss1 in the matlab command window. Elton,I guess that this very long book is Cichocki, Amari :"Adaptive blind signal and image processing" WILEY 2002. The other good and not so long reference is chapter 7 of "handbook of neural networks for signal processing" CRC PRESS(algorithm in bss1.m is covered there,i also uploaded this chapter here) . I also read some articles about cocktail party problem. So take a look how it works. I am waiting for reply.

I have a query.why the demixed signals are louder than the original?
