Abstract:

This work focuses on realizing a bin-wise adaptive Robust Generalized Sidelobe Canceller (RGSC) in the frequency domain in combination with a robust spatial estimation of the Signal-to-Interference-plus-Noise Ratio (SINR) for non-stationary signal mixtures. The final intention in this work is to capture the desired audio signal in presence of interference-plus-noise. For this purpose, using a microphone array is a good starting point, because by this spatial information can be exploited, and convenient and comfortable hands-free audio communication can be achieved by the microphone array.
