Adaptive beamforming with a Microphone Array

A robust and optimized system architecture has been developed and designed for adaptive beamformer with a Microphone Array. The system includes following subsystems - MMSE STSA Estimator, DOI (Direction of Interest) Estimator and an Adaptive Beamformer. The system architecture has been implemented and tested for Xtensa Processor which was configured for HiFi-2 DSP Standard for audio processing.
