In this paper, we propose a jointly-optimized stacked-two-stage speech enhancement. In the first stage, a convolutional recurrent network (CRN)-based masking is integrated with the signal analysis (fast Fourier transform (FFT)) and resynthesis (inver

We propose a multi-objective joint model of non-negative matrix factorization (NMF) and deep neural network (DNN) with a new loss function for speech enhancement. The proposed loss function (LMOFD) is a weighted combination of a frequency differentia

In this paper, we present a new supervised speech enhancement approach based on the cooperative structure of deep autoencoders (DAEs) as generative models and deep neural networks (DNN). The DAE is used as a nonlinear alternative to nonnegative matri

Interference mitigation is an important issue for global positioning system receivers. An anti-jamming system is proposed, which employs two wavelet packet transform (WPT)-based interference mitigation blocks. The proposed pre-/post-correlation mitig

In this paper, the authors describe a new pre-correlation mitigation technique for global positioning system (GPS) receivers. Proposed mitigation technique is based on wavelet packet coefficients thresholding. This technique employs adaptive threshol
