The first question that might arise is: What is the digital front end? The notion of the digital
front end (DFE) has been introduced by the author in several publications (eg [13]) …

Digital down converter (DDC) is one of the crucial components in digital radio receiver. The
working function of DDC is to convert the frequency translation from Intermediate Frequency …

BACKGROUND Wireless communication systems are widely deployed to provide various
communication services such as Voice, video, packet data, messaging, broadcast, etc …

In a previous work of the authors, it was shown that I/Q imbalance in the transmitter and
receiver chains significantly deteriorates the achievable amount of self-interference …

In this paper, we propose a configurable rotation matrix for Hyperbolic COordinate Rotation
DIgital Computer (CORDIC) to compute any logarithm and inverse logarithm. The rotation …

A hydrogen maser is a high-precision time measurement instrument with high frequency
stability and low frequency drift, which is widely used in satellite navigation, ground time …

This paper presents an implementation of a reconfigurable digital down converter (DDC)
that can translate high sample rate to lower sample rate signal on field-programmable gate …

The quality of audio recordings in outdoor environments is often degraded by the presence
of wind. Mitigating the impact of wind noise on the perceptual quality of single-channel …

The CONCERTO spectral-imaging instrument was installed at the Atacama Pathfinder
EXperiment (APEX) 12-meter telescope in April 2021. It has been designed to look at …

This paper proposes a novel design of intermediate frequency (IF) digital receiver for
wideband inverse synthetic aperture radar (ISAR) based on compressed sensing (CS). For …
