Inter-relay interference management schemes for wireless multi-user decode-and-forward relay networks
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)In this paper, two cooperative communications schemes with inter-relay interference (IRI) management are proposed for wireless multi-user decode-and-forward (DF) relay networks. The schemes are based on a DF half-duplex ... -
Performance analysis of cooperative communication system with feedback delay and channel estimation error
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)In this paper, we investigate the impact of feedback delay and channel estimation error (CEE) on the performance of wireless multi-user decode-and-forward (DF) relay systems in independent and non identically distributed ... -
Performance analysis of selective cooperation in amplify-and-forward relay networks over identical Nakagami-m channels
( Wiley Online Library , 2013 , Article)In cooperative communications, multiple relays between a source and a destination can increase the diversity gain. Because all the nodes must use orthogonal channels, multiple-relay cooperation becomes spectrally inefficient. ... -
Performance analysis of selective cooperation with fixed gain relays in Nakagami-m channels
( elsevier B.V. , 2012 , Article)Selecting the best relay using the maximum signal to noise ratio (SNR) among all the relays ready to cooperate saves system resources and utilizes the available bandwidth more efficiently compared to the regular all-relay ... -
Reactive relay selection in underlay cognitive networks with fixed gain relays
( IEEE , 2012 , Conference Paper)Best relay selection is a bandwidth efficient technique for multiple relay environments without compromising the system performance. The problem of relay selection is more challenging in underlay cognitive networks due to ...
