On Full-Duplex Radios With Modulo-ADCs
IEEE Open Journal of the Communications Society, 2021 Wireless full-duplex (FD) transceivers have become more commonplace in the recent years, enabled by improvements in hardware as well as in signal processing algorithms dedicated to self-interference (SI) mitigation.

Double-sampled cascaded sigma-delta modulator topologies for low oversampling ratios [PDF]
, 2006 This paper presents novel double-sampling cascaded sigma-delta modulator topologies for wideband applications. The proposed modulator structures employ finite impulse response (FIR) noise transfer function (NTF) to achieve the aggressive noise shaping ...

Learning of robust spectral graph dictionaries for distributed processing
EURASIP Journal on Advances in Signal Processing, 2018 We consider the problem of distributed representation of signals in sensor networks, where sensors exchange quantized information with their neighbors. The signals of interest are assumed to have a sparse representation with spectral graph dictionaries ...

Adversarial Robustness by One Bit Double Quantization for Visual Classification
IEEE Access, 2019 In this paper, we propose a novel robust visual classification framework that uses double quantization (dquant) to defend against adversarial examples in a specific attack scenario called “subsequent adversarial examples” where test images ...

Nonlinear optimization algorithm using monotonically increasing quantization resolution
ETRI Journal, 2023 We propose a quantized gradient search algorithm that can achieve global optimization by monotonically reducing the quantization step with respect to time when quantization is composed of integer or fixed-point fractional values applied to an ...
