audio demixing matlab code
Hello again,i am currently working on new algorithms for separation of mixed voice signals. Again it`s a 2x2 MIMO system and this time i take an approach of minimizing a mutual information of y ( size 2xN where N is number of samples) which contains the estimates of source signals. Minimizing a mutual information is a optimization problem and i use genetic algorithm for finding the optimal solution. Second algorithm is applied to a system that can be descirbied as 2x1 MISO system (2 sources and 1 sensor). Algorithm`s task is to separate mixed signals using only single record of their mixtures.To solve the problem i need 3 articles and i dont have access to ieeexplore base, can someone upload this articles for me?? Here is the list of articles:

Dear Swahlah, there is a whole chapter about blind decorrelation in the ebook by Cichocki, Amari:"Adaptive blind signal and image processing".
