Time Domain Optimization Techniques for Blind Separation of Non-stationary Convolutive Mixed Signals
13 years 6 months ago
This paper aims to solve the problem of Blind Signal Separation (BSS) in a convolutive environment based on output correlation matrix diagonalization. Firstly an extension of the ...
