Linear dispersion over time and frequency

2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004
High rate linear dispersion codes (LDC) for space time channels can support arbitrary numbers of transmit and receive antennas. In contrast to the one-to-one transformations used in interleaving, these codes disperse data in linear combinations over space and time. To improve performance of orthogonal frequency division multiplexing (OFDM) for wireless

Synchronization over fading dispersive channels

IEEE Transactions on Communications, 1988
An investigation is reported of an acquisition system for digital communication over fading dispersive channels that is optimum in the maximum-likelihood sense. A performance measure for the synchronizer in the acquisition mode is defined. Upper and lower bounds on the performance measure are derived.

Inherent Dispersion in Restitution Properties Over Space

2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006
Cardiac tissue heterogeneities can result in spatially dependent restitution properties. We propose a method for quantifying the dispersed nature of these restitution curves (RCs) over a large number of imaged pixels/locations. Cardiac propagation in response to point stimulation was recorded in cardiomyocyte monolayers with voltage-sensitive dye over ...

Generation of Over-Dispersed and Under-Dispersed Binomial Variates

Journal of Computational and Graphical Statistics, 1995
Abstract This article proposes an algorithm for generating over-dispersed and under-dispersed binomial variates with specified mean and variance. The over-dispersed/under-dispersed distributions are derived from correlated binary variables with an underlying continuous multivariate distribution.
