In the presence of background noise, the perceptual loudness of speech signal significantly decreases, resulting in the deterioration of intelligibility and clarity. In this letter, we propose a novel approach to enhance the perceived quality of the speech signal when the additive noise cannot be...
In this letter, we analyze the performance of a recently reported generalized blind channel estimation algorithm. The algorithm has a parameter called repetition index, and it reduces to two previously reported special cases when the repetition index is chosen as unity and as the size of received...
In this letter, we analyze the relationship between the change in the intensity value and the scale of an image feature, when a generalized function is used as the fidelity term in the total variation-based noise removal scheme. Based on the analysis, we propose a designing method of the fidelity...
