Abstract :
The generalized sidelobe canceller (GSC) beamformer is an effective and efficient technique for speech enhancement, whereas the design of beamformer is still a challenge in a reverberant environment, due to the difficulty of room impulse responses (RIRs) estimation. In this paper, we will study the design of GSC beamformer based on the RIRs estimated by image source method, which is a simple but effective method for room acoustics simulation.
