IMPLEMENTATION AND EXPERIMENTAL RESULTS OF A CHIP FOR THE SEPARATION OF MIXED AND FILTERED SIGNALS

We describe an algorithm and chip implementation for separating a mixture of unknown, but independent, temporal signals in static and dynamic environments. The proposed algorithm, which is a simple modification of the Herault and Jutten (HJ) algorithm, proved to be robust to parameter variations in both cases. We present chip test results to quantify the performance of the modified algorithm in static and dynamic (mixing and filtering) environments. Moreover, experiments of separating two speech or two music signals in English-English, English-Japanese, and English-Arabic have demonstrated successful performance.
