Comparing Haar-Hilbert and Log-Gabor Based Iris Encoders on Bath Iris Image Database
This papers introduces a new family of iris encoders which use 2-dimensional Haar Wavelet Transform for noise attenuation, and Hilbert Transform to encode the iris texture. In orde...

Parallel constrained coding with application to two-dimensional constraints
A parallel constrained coding scheme is considered where p-blocks of raw data are encoded simultaneously into q tracks such that the contents of each track belong to a given const...

Multiple Access Channels with State Information Known at Some Encoders
We consider a multiple access channel (MAC) with channel state information (CSI) non-causally known at some encoders. For simplicity of exposition, we focus on a two-encoder model...

Chaotic Digital Encoding for 2D Trellis-Coded Modulation
—In this paper, nonlinear digital filters with finite precision are analyzed as recursive systematic convolutional (RSC) encoders. An infinite impulse response (IIR) digital filt...

An evolutionary approach for reducing the switching activity in address buses
In this paper we present two new approaches based on genetic algorithms (GA) to reduce power consumption by communication buses in an embedded system. The first approach makes it ...
