Re: single blind signal separation matlab

needed matlab code aND OTHER DATA RELATED TO BLIND SIGNAL SEPERATION USING ICA:?:
 

hi Jkormanski,

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

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.

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 ?

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


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