Learning-Based Design of Measurement Matrix with Inter-Column Correlation for Compressive Sensing

Mahdi Parchami, Hamidreza Amindavar, Wei-Ping Zhu
ICASSP 2018accepted

In this paper, a new approach for the design of measurement matrix, Φ, for compressive sensing (CS) in a generic context is proposed. In accordance with well-known classical CS theory, we take the elements of Φ to be random, yet, we include correlations within the elements of the individual columns…

Speech dereverberation using linear prediction with estimation of early speech spectral variance

Mahdi Parchami, Wei-Ping Zhu, Benoît Champagne
ICASSP 2016accepted

In this paper, we present a new dereverberation algorithm based on the weighted prediction error (WPE) method. In contrast to the conventional WPE method which alternatively estimates the reverberation prediction weights and early speech spectral variance, the proposed algorithm estimates the latter…
