Increasing the Robustness of Acoustic Multichannel Equalization by Means of Regularization
The performance of acoustic multichannel equalization techniques, which are based on estimating and inverting the room impulse responses (RIRs) between the source and the microphone array, is known to be very sensitive to estimation errors of the RIRs. In order to increase the robustness, it has been proposed to use regularization with the aim of decreasing the energy of the inverse filters. Th...
متن کاملRegularization in global sound equalization based on effort variation.
Sound equalization in closed spaces can be significantly improved by generating propagating waves that are naturally associated with the geometry, as, for example, plane waves in rectangular enclosures. This paper presents a control approach termed effort variation regularization based on this idea. Effort variation equalization involves modifying the conventional cost function in sound equaliz...
متن کاملIncorporating the Noise Statistics in Acoustic Multi-channel Equalization
Acoustic multi-channel equalization techniques, such as the regularized partial multi-channel equalization technique based on the multiple-input/output inverse theorem (RP-MINT), are able to achieve a high dereverberation performance in the presence of room impulse response perturbations but may lead to additive noise amplification. This paper proposes to directly extend the RP-MINT technique b...
متن کاملAn 8-16 Gb/s, 0.65-1.05 pJ/b, Voltage-Mode Transmitter With Analog Impedance Modulation Equalization and Sub-3 ns Power-State Transitioning
Serial link transmitters which efficiently incorporate equalization, while also enabling fast power-state transitioning to leverage dynamic power scaling, are necessary to meet future systems’ I/O requirements. This paper presents a scalable voltage-mode transmitter which offers low static power dissipation and adopts an impedance-modulated 2-tap equalizer with analog tap control, thereby obvia...
متن کاملInstrumental and Perceptual Evaluation of Dereverberation Techniques Based on Robust Acoustic Multichannel Equalization
Dereverberation techniques based on acoustic multichannel equalization, such as the relaxed multichannel least squares (RMCLS) technique and the partial multichannel equalization technique based on the multiple-input/output inverse theorem (PMINT), are known to be sensitive to room impulse response perturbations. In order to increase their robustness, several methods have been proposed, e.g., u...
