This paper describes a novel technique for decorrelating the stereo signals in stereophonic acoustic echo cancellation (AEC) systems. At present, most teleconferencing systems use a single full-duplex audio channel for voice communications. However, in order to introduce spatial realism, future teleconferencing systems are expected to have more than one channel (at least stereo with two channel...

In this paper, we study signal detection in multi-input-multi output (MIMO) communications system with non-Gaussian noises such as Middleton Class A noise, Gaussian mixtures and alpha stable distributions, using several deep neural network-based detector models FULLYCONNECTED DETNET detector. By applying information theoretic criterion of Maximum Correntropy , SVD analysis on the channel matrix...

A stereophonic enhancement system is described which expands the perceived width of the stereo sound image. The system accepts electrical audio signals comprising a two-channel (left and right) stereo pair and produces enhanced left and right stereo signals for use with conventional two-channel audio recording and playback systems. The system includes control circuitry which monitors the dissim...

In this paper, we will analyze the energy efficient power loading in MIMO-SVD architecture. Existing power loading schemes are developed on assumption that a scheduler possesses perfect channel state information (CSI). But we take into account the effects of channel estimation error (CEE) and propose a robust energy-efficient power loading for MIMO system under imperfect CSI. We propose two alg...

The paper is concerned with the hidden dynamic state estimation in linear discrete-time stochastic systems in presence of Gaussian noises. The associated with the state-space model estimator is known as the Kalman filter (KF). One of the shortcomings of this recursive algorithm is its numerical instability with respect to roundoff errors. Since the appearance of the KF in 1960s, much effort has...

The Geometric Mean Decomposition (GMD) based transceiver design has gained huge attention in the recent past as it provides an optimal solution in terms of BER and capacity. GMD technique has been widely adopted for the joint transceiver design as it converts the MIMO channel into identical and parallel SISO channels hence avoiding the necessity for bit loading and also achieves minimized bit e...
