Discrete cosine transform (DCT) has been proven to be a good approximation to the
Karhunen-Loeve Transform (KLT) and has similar properties to the discrete Fourier …

A speech enhancement method in the DCT domain using a new soft thresholding strategy is
proposed. Exploiting the behaviour of the amplitude distribution of the DCT coefficients, a …

This paper presents a comprehensive study on speech enhancement (SE) techniques,
particularly focusing on the utilization of the discrete cosine transform (DCT) in the …

This paper presents a novel algorithm of speech enhancement using data adaptive
softthresolding technique. The noisy speech signal is decomposed into a finite set of band …

Conventional multiband speech enhancement involves splitting the spectrum into various
frequency bins and performing speech enhancement in each band independently. However …

This paper introduces a new speech enhancement method using soft thresholding with a
Discrete Cosine Transform (DCT) and Empirical Mode Decomposition (EMD) based hybrid …

In order to improve the performance of a speech enhancement system, Plapous introduced
a novel method called two-step noise reduction (TSNR) technique to refine the a priori SNR …

An improved soft threshold method for speech enhancement in the Discrete Cosine
Transform (DCT) domain is proposed in this paper. Rather than apply a threshold only to …
