Signal Transmission and Processing Technology of a Microphone Array-Based Blind Speech Separation System

Abstract： In this paper，an experimental platform of blind speech separation based on microphone array has been built. The time-division multiplexed (TDM) of microphone array and the data transmission of combining DMA and McBSP are introduced emphatically.  

Key words：microphone array; blind speech separation; TDM; McBSP; DMA
