Sparsely Localized Time-Frequency Energy Distributions for Multi-Component LFM Signals

SPL Volume 27 | 2020
SPL Featured Articles

This letter presents a high resolution method which separates close components of a multi-component linear frequency modulated (LFM) signal and eliminates their Cross-Terms (CTs). We first investigate the energy distribution of the Auto-Terms (ATs) and CTs in ambiguity plane.

Adaptive Reverberation Absorption Using Non-Stationary Masking Components Detection for Intelligibility Improvement

SPL Volume 27 | 2020
SPL Featured Articles

This letter proposes a new time domain absorption approach designed to reduce masking components of speech signals under noisy-reverberant conditions. In this method, the non-stationarity of corrupted signal segments is used to detect masking distortions based on a defined threshold.
