Cooperative relaying is one of the promising technology which is used to improve coverage and spatial diversity. A new relay strategy, the N Best-Relay Selection scheme is proposed to improve the bandwidth penalty and to increase the spatial diversity by using a sub-optimal allocation for the relay relative distance between the source and destination in a multi-hop cooperative systems. A single...

In this paper, the performance of decode –and-forward relaying over multiple fading channels is been analyzed. Here at first overviewed traditional relaying techniques and compared it with coded cooperative relaying. BER performance the different schemes are analyzed and the results shows that coded cooperative relaying give better performance in terms of BER analysis. A new technique called ne...

by Glenn J. Bradford Increasing data rates in wireless devices is particularly challenging due to the presence of many impairments in the medium, including multipath fading. Diversity techniques are a means of increasing transmission reliability in multipath environments. This thesis focuses on cooperative diversity, a concept that obtains spatial diversity via relaying. Cooperative diversity e...

In this paper some simple cooperative relaying strategies which rely on the exploitation of the Delay Diversity technique and the Maximal Ratio Combining (MRC) receive diversity algorithm are proposed for a DVB-SH compliant hybrid satellite/terrestrial network. These strategies are investigated in a public emergency scenario where the adoption of an integrated heterogeneous network combined wit...

Labeling diversity is an efficient technique recently proposed in the literature and aims to improve the Bit Error Rate (BER) performance of Wireless Local Area Network (WLAN) systems with two transmit and two receive antennas without increasing the transmit power and bandwidth requirements. In this paper, we employ labeling diversity with different space-time channel codes such as convolutiona...

Recently, cooperative diversity has emerged as a means of providing gains from spatial diversity to devices with single antennas. Yet, the performance of these protocols remains limited in symmetric networks. In this paper, we investigate the performance of a novel “detached” cooperative diversity protocol that is designed for asymmetric networks, both in terms of outage probability and frame e...
