TSTNN: Two-stage Transformer based Neural Network for Speech Enhancement in the Time Domain
Kai Wang, Bengbeng He, Wei-Ping Zhu
In this paper, we propose a transformer-based architecture, called two-stage transformer neural network (TSTNN) for end-to-end speech denoising in the time domain. The proposed mod…
On the Use of Audio Fingerprinting Features for Speech Enhancement with Generative Adversarial Network
Farnood Faraji, Yazid Attabi, Benoit Champagne +1
The advent of learning-based methods in speech enhancement has revived the need for robust and reliable training features that can compactly represent speech signals while preservi…
Genetic Algorithm Optimized Support Vector Machine in NOMA-Based Satellite Networks with Imperfect CSI
Xiaojuan Yan, Kang An, Cheng-Xiang Wang +3
With the help of a power-domain non-orthogonal multiple access (NOMA) scheme, satellite networks can simultaneously serve multiple users within limited time/spectrum resource block…
S-ConvNet: A Shallow Convolutional Neural Network Architecture for Neuromuscular Activity Recognition Using Instantaneous High-Density Surface EMG Images
Md. Rabiul Islam, Daniel Massicotte, Francois Nougarou +2
The concept of neuromuscular activity recognition using instantaneous high-density surface electromyography (HD-sEMG) images opens up new avenues for the development of more fluid…
Joint Doppler and Channel Estimation with Nested Arrays for Millimeter Wave Communications
Xiaohuan Wu, Wei-Ping Zhu, Min Lin +1
Channel estimation is essential for precoding/combining in millimeter wave (mmWave) communications. However, accurate estimation is usually difficult because the receiver can only…
Speech Enhancement in Adverse Environments Based on Non-stationary Noise-driven Spectral Subtraction and SNR-dependent Phase Compensation
Md Tauhidul Islam, Asaduzzaman, Celia Shahnaz +2
A two-step enhancement method based on spectral subtraction and phase spectrum compensation is presented in this paper for noisy speeches in adverse environments involving non-stat…
Enhancement of Noisy Speech Exploiting an Exponential Model Based Threshold and a Custom Thresholding Function in Perceptual Wavelet Packet Domain
Md Tauhidul Islam, Celia Shahnaz, Wei-Ping Zhu +1
For enhancement of noisy speech, a method of threshold determination based on modeling of Teager energy (TE) operated perceptual wavelet packet (PWP) coefficients of the noisy spee…
Enhancement of Noisy Speech with Low Speech Distortion Based on Probabilistic Geometric Spectral Subtraction
Md Tauhidul Islam, Celia Shahnaz, Wei-Ping Zhu +1
A speech enhancement method based on probabilistic geometric approach to spectral subtraction (PGA) performed on short time magnitude spectrum is presented in this paper. A confide…
Modeling of Teager Energy Operated Perceptual Wavelet Packet Coefficients with an Erlang-2 PDF for Real Time Enhancement of Noisy Speech
Md Tauhidul Islam, Celia Shahnaz, Wei-Ping Zhu +1
In this paper, for real time enhancement of noisy speech, a method of threshold determination based on modeling of Teager energy (TE) operated perceptual wavelet packet (PWP) coeff…
A Divide and Conquer Strategy for Musical Noise-free Speech Enhancement in Adverse Environments
Md Tauhidul Islam, Celia Shahnaz, Wei-Ping Zhu +1
A divide and conquer strategy for enhancement of noisy speeches in adverse environments involving lower levels of SNR is presented in this paper, where the total system of speech e…
A High-resolution DOA Estimation Method with a Family of Nonconvex Penalties
Xiaohuan Wu, Wei-Ping Zhu, Jun Yan
The low-rank matrix reconstruction (LRMR) approach is widely used in direction-of-arrival (DOA) estimation. As the rank norm penalty in an LRMR is NP-hard to compute, the nuclear n…
Atomic Norm Based Localization of Far-Field and Near-Field Signals with Generalized Symmetric Arrays
Xiaohuan Wu, Wei-Ping Zhu, Jun Yan
Most localization methods for mixed far-field (FF) and near-field (NF) sources are based on uniform linear array (ULA) rather than sparse linear array (SLA). In this paper, we prop…
Security-Reliability Trade-off Analysis of Multi-Relay Aided Decode-and-Forward Cooperation Systems
Jia Zhu, Yulong Zou, Benoit Champagne +2
We consider a cooperative wireless network comprised of a source, a destination and multiple relays operating in the presence of an eavesdropper, which attempts to tap the source-d…
Relay-Selection Improves the Security-Reliability Trade-off in Cognitive Radio Systems
Yulong Zou, Benoit Champagne, Wei-Ping Zhu +1
We consider a cognitive radio (CR) network consisting of a secondary transmitter (ST), a secondary destination (SD) and multiple secondary relays (SRs) in the presence of an eavesd…
