Most of the current approaches for speech enhancement (SE) using deep neural network (DNN) face a number of limitations: they do not exploit information contained in the phase spectrum while their high computational complexity and memory requirements

A deep spectrum sculpting is necessary to enable coexistence between a cognitive radio (CR) user and a licensed user which has low dynamic range and is susceptible to interferences. In this paper, we propose to use joint filter-bank based multicarrie

Orthogonal chirp division multiplexing (OCDM) is a spread spectrum technique that leverages the orthogonality of cyclically shifted linear chirp signals to maximize spectral efficiency. However, since each chirp spans the entire signal band, the only

An objective of this article is to design a novel communication system that is capable of offering substantial improvement in channel capacity compared to band-limited (BL) communication systems, when constrained by the same spectral mask. To this en

Faster-than-Nyquist signaling (FTNS) is capable of improving the spectral efficiency (SE) of communication systems. However, for conventional single-carrier FTNS (SC-FTNS) in which only symbol interval is reduced, the increase of SE is very limited d

The problem of blind audio source separation (BASS) in noisy and reverberant conditions is addressed by a novel approach, termed Global and LOcal Simplex Separation (GLOSS), which integrates full- and narrow-band simplex representations. We show that

Signal processing faces the quandary of not being able to separate non-stationary noise from speech signal. Traditional methodologies relied on spectral subtraction for the same; however, such techniques relied on approximation of spectral mask of th
