Tone detection of non-uniformly undersampled signals with frequency excision
We address the problem of detecting and locating narrowband tones in an undersampled signal. It is known that uniformly undersampled signals exhibit frequency aliasing, whereby th...

Social norm and long-run learning in peer-to-peer networks
We start by formulating the resource sharing in peer-to-peer (P2P) networks as a random-matching gift-giving game, where self-interested peers aim at maximizing their own long-ter...

ML decoding in decode-and-forward based cooperative communication system
Abstract— In this paper, we derive a maximum-likelihood (ML) decoder of the decode-and-forward (DF) protocol utilizing an arbitrary complex-valued M-point constellation. Existing...

Dual frame of frequency warping operators
In this work we introduce the dual frame operator relative to the aliasing compensated frequency warping operator for nonsmooth warping functions. Except for approximation errors,...

Efficient coherent phase quantization for audio watermarking
The weighted overlap add (WOLA) technique is routinely used in audio processing to avoid introducing audible clicks. This process introduces inter-dependencies between WOLA coeffi...

Analysis of non-coherent code tracking for NPSK systems in presence of noise and fading
Given the recent interest in non-binary forms of spreading sequences, there is a gap in knowledge on code tracking techniques for noise-like spreading codes. This paper presents t...

Degenerate Unmixing Estimation Technique using the Constant Q Transform
The Degenerate Unmixing Estimation Technique (DUET) is a Blind Source Separation (BSS) algorithm for stereo audio. DUET depends on an amplitude-phase 2d histogram built from the d...

Exposing duplicated regions affected by reflection, rotation and scaling
A commonly considered image manipulation is to conceal undesirable objects or people in the scene with a region of pixels copied from the same image. Forensic mechanisms aimed at ...
