Performance analysis of dual source transfer-function generalized sidelobe canceller
In this work, we evaluate the performance of a recently proposed adaptive beamformer, namely Dual source Transfer-Function Generalized Sidelobe Canceller (DTF-GSC). The DTF-GSC is useful for enhancing a speech signal received by an array of microphones in a noisy and reverberant environment. We demonstrate the applicability of the DTF-GSC in some representative reverberant and non-reverberant e...
متن کاملJoint noise reduction and acoustic echo cancellation using the transfer-function generalized sidelobe canceller
Man machine interaction requires an acoustic interface for providing full duplex hands-free communication. The transfer-function generalized sidelobe canceller (TF-GSC) is an adaptive beamformer suitable for enhancing a speech signal received by an array of microphones in a noisy and reverberant environment. When an echo signal is also present in the microphone output signals, cascade schemes o...
متن کاملModulated Lapped Transform Generalized Sidelobe Canceller
Continuing improvements in analog and digital technology has made elemental digital beamforming (DBF) for sensor arrays a reality. Weak signal reception enhancement can be achieved through the adaptive suppression of potentially time-varying interference in operational environments. Utilizing all the degrees of freedom (DoF's) of an adaptive elemental DBF array with a large number of elements i...
متن کاملA novel wavelet-based generalized sidelobe canceller
This paper presents a novel narrowband adaptive beamformer with the generalized sidelobe canceller (GSC) as the underlying structure. The new beamformer employs the regular M -band wavelet lters in the design of the blocking matrix of the GSC, which, as justi ed analytically, can indeed block the desired signals as required, provided the wavelet lters have su ciently high regularity. Additional...
متن کاملRobustness Analysis of Gsvd Based Optimal Filtering and Generalized Sidelobe Canceller for Hearing Aid Applications
Multi-microphone noise reduction techniques for hearing aid applications go together with the use of small-sized arrays. Considerable noise reduction can be achieved with such arrays, but at the expense of an increased sensitivity to model errors or a priori assumptions. We evaluate the robustness of the Generalized Sidelobe Canceller (GSC) and a Generalized Singular Value Decomposition (GSVD) ...
