Blind Estimation of Perceptual Quality for Modern Speech Communications
Modern speech communication technologies expose users to perceptual quality degradations that were not experienced earlier with conventional telephone systems. Since perceived speech quality is a major contributor to the ...
Cross-layer design of admission control policies in code division multiple access communications systems utilizing beamforming
To meet growing demand for wireless access to multimedia traffic, future generations of wireless networks need to provide heterogenous services with high data rate and guaranteed quality-of-service (QoS). Many enabling ...
Link Adaptation for Energy Constrained Networks
Relay terminals are often used in tandem in sensor networks to lessen nodal communication burden. In this light we investigate the problem of power allocation amongst nodes in a relay network in order to maximize the overall ...
Reliability-based Detection of Variable-rate Space-time Block Codes
We present a new sub-optimal near-maximum-likelihood (ML) detection method for the family of variable-rate space-time block codes (VRSTBC). The proposed detection method is based on the concept of symbol reliability and ...
A new efficient CSI signalling strategy for MMR Systems with optimal detection
We present a new Channel State Information (CSI) signalling strategy for single- branch Mobile Multihop Relay (MMR) systems. This novel signalling strategy reduces the signalling overhead at each relay by at least 50%, ...
