Sparse Solution Trade-offs in GMP DPD: A Least Squares Thresholding Approach
Ellison Murray
Power amplifiers (PAs) in satellite communication systems introduce nonlinear distortion, degrading spectral fidelity. Digital pre-distortion linearizes the PA response, but full-c…

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…

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-…
