Covert Routing with DSSS Signaling Against Cycle Detectors
Swapnil Saha, Rahul Aggarwal, Fikadu Dagefu +4
This paper investigates covert multi-hop communication in wireless networks where an adversary employs a cyclostationary (cycle) detector to reveal hidden transmissions. The covert…
A Low-Complexity Speech Codec Using Parametric Dithering for ASR
Ellison Murray, Morriel Kasher, Predrag Spasojevic
Dithering is a technique commonly used to improve the perceptual quality of lossy data compression. In this work, we analytically and experimentally justify the use of dithering fo…
Design and Implementation of Parametrized Look-Up Tables for Post-Correction of Oversampling Low-Resolution ADCs
Morriel Kasher, Michael Tinston, Predrag Spasojevic
We propose a framework for the design, optimization, and implementation of Look-Up Tables (LUTs) used to recover noisy, oversampled, quantized signals given a parametric input mode…
Quantized Signal Recovery with Interference via Parametrized Look-Up Tables
Morriel Kasher, Michael Tinston, Predrag Spasojevic
Efficient all-digital post-correction of low-resolution analog-to-digital converters can be achieved by using Look-Up Tables (LUTs). The performance of a LUT can be optimized by in…
Optimizing Audio Compression Through Entropy-Controlled Dithering
Ellison Murray, Morriel Kasher, Predrag Spasojevic
This paper explores entropy-controlled dithering techniques in audio compression, examining the application of standard and modified TPDFs, combined with noise shaping and entropy-…
