A Robust ADMM-Based Optimization Algorithm For Underwater Acoustic Channel Estimation
Accurate estimation of the Underwater acoustic (UWA) is a key part of underwater communications, especially for coherent systems.
LMD: A Learnable Mask Network to Detect Adversarial Examples for Speaker Verification
It utilizes score variation as an indicator to detect adversarial examples, where the score variation is the absolute discrepancy between the ASV scores of an original audio recording and its transformed audio synthesized from its masked complex spectrogram.
Symmetric Saliency-based Adversarial Attack To Speaker Identification
Adversarial attack approaches to speaker identification either need high computational cost or are not very effective, to our knowledge.
IF equation: a feature extractor for high-concentration time-frequency representation of mixed signals
By the analysis of the properties of the IF equation, we prove that a good IF equation can unify the well-known IF and group delay estimators and provides an effective way to characterize the mixture of time-varying and frequency-varying signals.
High-resolution chirplet transform: from parameters analysis to parameters combination
The standard chirplet transform (CT) with a chirp-modulated Gaussian window provides a valuable tool for analyzing linear chirp signals.
