UWB MIMO cooperative relay systems: BER analysis and relay regions

Abstract

In this paper, bit error rate (BER) analysis is presented for ultra-wideband (UWB) multiple-input multiple-output (MIMO) cooperative relay systems, where partial channel state information (CSI) is only available at the receiver side. In the analysis, decouple-and-forward (DCF) and decode-and-forward (DF) relaying schemes are considered. For these schemes, the relay regions, in which cooperative relaying outperforms direct transmission, and the effects of power optimization are studied through numerical results.Index Terms-Ultra-wideband (UWB), cooperative relaying, multipleinput multiple-output (MIMO).

Relay-assisted UWB communications: links characterization and power allocation

“…An analysis through characteristic functions and numerical evaluations has been proposed in [12] by modeling the links according to IEEE 802. 15.4a standards, while in [13] UWB multiple-input multiple-output (MIMO) systems with power allocation have been investigated, where each link is modeled with tappeddelay-lines, Nakagami-m fading, and exponential power delay profile.…”

Performance analysis of multiple-input multiple-output relay networks based impulse radio ultra-wideband

“…Based on a modified Saleh-Valenzuela model [6], the IEEE 802.15.4a channel modeling subgroup [1] has provided channel models for UWB systems where the multipath components arrive in a random number of clusters; within each, a random number of rays is considered. The effectiveness of cooperative diversity was extended to the context of IR-UWB systems in [7][8][9][10]. Employing DF and AF protocols, the authors in [7,8] present the construction of space-time (ST) codes suitable for IR-UWB.…”

“…Employing DF and AF protocols, the authors in [7,8] present the construction of space-time (ST) codes suitable for IR-UWB. In [9], bit error rate (BER) analysis is presented for UWB-MIMO cooperative relay systems under stochastic tapped-delayline propagation channel model. In [10], the authors analyzed the bit error probability of time-hopping UWB relay networks under IEEE 802.15.4a channel models.…”

A New Compact UWB Microstrip BPF for Wireless Communication Using DGS

“…The ultra-wideband technology play vital role in the field of wireless communication systems after allowed unlicensed operation of RF band from 3.1GHz to 10.60GHz in the year 2002 [1]. It has numerous demands in wireless communication such as transmitting high data rate and consumes low power while transmitting.…”
