Contact-free vital-signs monitoring enabled by radio frequency (RF) sensing is gaining
increasing attention, thanks to its non-intrusiveness, noise-resistance, and low cost …

A linear-in-the-parameters nonlinear filter consists of a functional expansion block, which
expands the input signal to a higher dimensional space nonlinearly, followed by an adaptive …

In this contribution, we introduce a novel approach to noise-robust acoustic echo
cancellation employing a complex-valued Deep Neural Network (DNN) for postfiltering. In a …

The digital implementation of a nonlinear audio circuit often employs the Newton-Raphson
(NR) method for solving the corresponding system of implicit ordinary differential equations …

In this letter, we introduce a novel approach for nonlinear acoustic echo cancellation. The
proposed approach uses the principle of transfer learning to train a neural network that …

The paper studies a novel family of nonlinear filters based on Chebyshev polynomials of the
first kind, the Chebyshev nonlinear filters. This family shares many of the characteristics of …

The paper discusses a novel sub-class of linear-in-the-parameters nonlinear filters, the
Legendre nonlinear filters. The novel sub-class combines the best characteristics of …

Acoustic Echo Cancellation (AEC) whose aim is to suppress the echo originated from
acoustic coupling between loudspeakers and microphones, plays a key role in voice …

Several digital signal processing approaches, generally referred to as Virtual Analog (VA)
modeling, are currently under development for the software emulation of analog audio …

This paper introduces a new class of nonlinear filters for nonlinear acoustic echo
cancellation (NLAEC) based on Hermite nonlinear filters (HNFs), which is a sub-class of …
