Performance Lower Bounds for Existing and New Uncoded Digital Watermarking Modulation Techniques
Abstract. Many coded digital watermarking systems development requires first the selection of a (uncoded) modulation technique to be part of a coded architecture. Therefore, perfo...

Delta-sigma modulator topologies with high immunity to pattern noise
This paper addresses the problem of pattern noise encountered in single-stage delta-sigma modulators in the presence of a DC input signal. By utilizing state-space matrices, we ex...

Analysis of Differential Unitary Space-Time Modulation over Non-Identical MIMO Channels
Abstract— We present an analytical study on the error performance of differential unitary space-time modulation (DUSTM) over multiple-input multiple-output (MIMO) channels with n...

Lossless and Near-Lossless Audio Compression Using Integer-Reversible Modulated Lapped Transforms
We present a simple lossless audio codec, composed of an integer-reversible modulated lapped transform (MLT) followed by a backward-adaptive run-length/Golomb-Rice (RLGR) encoder....
