Performance of relay-assisted soft handover
(
IEEE
, 2009 , Conference Paper)
This paper examines the effect of relay-assisted soft handover on the performance of the uplink communication in the third generation mobile networks. We focus on users which are traveling over two cell boundaries in a ...
On relay assignment in network-coded cooperative systems
(
IEEE
, 2011 , Article)
We consider in this paper relay assignment for cooperative systems with multiple two-way relay channels. The nodes corresponding to one two-way relay channel (henceforth referred to as pair) communicate with each other ...
On the Performance of RIS-Assisted Dual-Hop UAV Communication Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
In this paper, to further improve the coverage and performance of unmanned aerial vehicle (UAV) communication systems, we propose a reconfigurable intelligent surface (RIS)-assisted UAV scheme where an RIS installed on a ...
Average ber of multihop communication systems over fading channels
(
IEEE
, 2003 , Conference Paper)
Multihop transmission is a way to attain broader coverage by splitting the communication link from the source to the destination into several, possibly shorter links/hops. This paper presents an expression for the moment ...
Threshold-based relaying in coded cooperative networks
(
IEEE
, 2011 , Article)
In cooperative communications, error propagation at the relay nodes degrades the diversity order of the system. To combat that effect, we present a novel technique to control error propagation at the relays, which is ...
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 ...
Asymptotic BER analysis of FSO with multiple receive apertures over M-distributed turbulence channels with pointing errors
(
Optical Society of American (OSA)
, 2014 , Article)
In this paper, we consider a free-space optical (FSO) communication with multiple receive apertures over M-distributed turbulence channels with pointing errors. In particular, we consider two different combining schemes ...
Performance analysis of selective cooperation in underlay cognitive networks over Rayleigh channels
(
IEEE
, 2011 , Conference Paper)
Underlay cognitive networks should follow strict interference thresholds to operate in parallel with primary networks. This constraint limits their transmission power and eventually the area of coverage. Therefore, it is ...
On the Error Performance of Non-orthogonal Multiple Access Systems
(
IEEE Computer Society
, 2020 , Conference Paper)
Unlike orthogonal multiple access schemes, non-orthogonal (NOMA) ones have arisen as an appealing solution to meet the requirements of the upcoming era of massive connectivity. In NOMA schemes, users are allowed to ...
Relay assignment in network-coded cooperative systems with M-PSK modulation over asymmetric channels
(
IEEE
, 2010 , Conference Paper)
We consider in this paper relay assignment for cooperative systems with multiple two-way relay channels. The nodes corresponding to one two-way relay channel (henceforth referred to as pair) communicate with each other ...
