Directional descriptors using zernike moment phases for object orientation estimation in underwater sonar images
Conventional methods for rotation angle estimation are not very robust to variations in object shape or intensity. However in real object recognition scenarios like in underwater ...

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,...

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...
