The design of high-efficiency low-complexity detection schemes for ultrawide bandwidth (UWB) systems is highly challenging. This paper proposes a reduced-rank adaptive multiuser detection (MUD) scheme that is operated in least bit-error-rate (LBER) principles for hybrid direct-sequence time-hopping UWB (DS-TH UWB) systems. The principal component analysis (PCA)-assisted rank-reduction technique is...
We study the physical layer design of a distributed time-division multiple access (TDMA) protocol for wireless body area networks (WBAN). The distributed TDMA scheme is derived from a bio-inspired algorithm known as Pulse-Coupled Oscillator (PCO), in which each node in the network updates its state based on its knowledge of the neighborhood. ON-OFF ultra wide band (UWB) modulation is used by the sensors...
Ultra wideband (UWB) is considered to be one of the most promising short range wireless communication technologies; due to its high data rate, low cost and low energy consumption. Despite its enviable benefits, the performance of UWB systems may be degraded due to the presence of inband narrow band interference (NBI) signals and this performance must be carefully investigated. To this end; we provide...
Ultra-wideband (UWB) is a powerful technology for high data rate short-range wireless communications and position location applications. The application of Time-reversal (TR) technology, due to its temporal and spatial focusing characteristic, can greatly improve the performance of UWB wireless communication. In order to take full advantage of TR-UWB technology, it is required to understand the propagation...
