A simple software method to increase the duty-cycle resolution in a digital pulse width modulation (DPWM)-controlled power ...

Abstract: In this work, we investigate the performance of geometric constellation shaping for highorder coded quadrature amplitude modulation (QAM) over an additive white Gaussian noise (AWGN) channel ...

A friend of mine is producing a series of HOWTO videos for an open source project, and discovered that he needed a better ...

Gray code is a systematic ordering of binary numbers in a way that each successive value differs from the previous one in ...

Modulation advances have fueled more efficient use of bandwidth, although conventional modulation formats still require allowance for upper and lower sidebands around the carrier frequency. Ultra ...

Abstract: This paper presents a D-band direct-digital transmitter that employs RF-DACs to perform modulation in the RF domain. It achieves 64-QAM with a maximum data rate of $48 \mathrm{~Gb} / \mathrm ...

Atomic-scale imperfections in graphene transistors generate unique wireless fingerprints that cannot be copied or predicted, ...
