Real-Time Noise Cancelling Approach on Innovations-Based Whitening Application to Adaptive FIR RLS in Beamforming Structure
نویسنده
چکیده
Based on the two-microphone approach, the applications are characterized as three methods, which are based on identification of unknown system in acoustic channels, adaptive speech beamforming and adaptive noise cancellation. It can be described as generalized three sub-block diagram as shown in Fig. 2, where it is shown as three processing stages of (1) kepstrum (complex cepstrum), (2) beamforming and (3) ANC and also two structures of beamforming and ANC.

متن کاملTDL-based Wideband Beamforming for Radio Sources Close to the Array Endfire
Uniform linear array (ULA)-based tapped-delay line (TDL) structure has good performance metrics when the signal sources are located at the middle angles. It offers poor performance when the signal sources are close to the array endfire. In this paper, a new approach is proposed which offers higher performance and desired beamforming on TDL structure when the wideband uncorrelated radio sources ...
