SVD-Based Optimal Filtering Technique for Noise Reduction in Hearing Aids Using Two Microphones
EURASIP Journal on Advances in Signal Processing, 2002 We introduce a new SVD-based (Singular value decomposition) strategy for noise reduction in hearing aids. This technique is evaluated for noise reduction in a behind-the-ear (BTE) hearing aid where two omnidirectional microphones are mounted in an ...

Robust Adaptive Beamforming against Signal Steering Vector Mismatch and Jammer Motion
International Journal of Antennas and Propagation, 2015 Since adaptive beamformer suffers from output performance degradation in the presence of interference nonstationarity and signal steering vector mismatch, a novel robust null broadening adaptive beamforming is proposed. The proposed method is realized by

Dual-Mic Speech Enhancement Based on TF-GSC with Leakage Suppression and Signal Recovery
Applied Sciences, 2021 The transfer function-generalized sidelobe canceller (TF-GSC) is one of the most popular structures for the adaptive beamformer used in multi-channel speech enhancement. Although the TF-GSC has shown decent performance, a certain amount of steering error
