Coherence Diversity: a new source of gains in wireless networks

Dallas Section – IEEE Communications & Vehicular Technology – Please Note 04/16/24 Date

Dallas CVT April 2024 update

Our spring 2024 meetings continue with our regular Third Tuesday slot for April.

For May we are considering a social activity, tentatively a Friday evening of AA Baseball with the Frisco Roughriders. Watch your email for a poll.  We need a good head count for planning purposes.

Tuesday, April 16, 2024, 12:00 PM to 1:00 PM at UT Dallas SPN.1

Topic: Coherence Diversity: a new source of gains in wireless networks

Abstract:

Due to differences in mobility and local scattering, the links in a wireless network can experience disparities in coherence time that, in the past, were mostly ignored in the modeling and analysis of networks. We show that these coherence disparities can be a source of capacity gains (denoted “coherence diversity”) that are distinct and independent of classical gains such as spatial multiplexing, beamforming, and multiuser diversity. A product superposition is introduced that can exploit these differences in coherence and yield gains in degrees of freedom. It is shown that differences in coherence bandwidth also yield a similar gain. Time permitting, non-uniformity of CSIT under coherence disparity and disparity in spatial coherence will be discussed. Several open problems in the broad area of coherence diversity will be highlighted.
