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 ...
Joint statistics of partial sums of ordered exponential variates and performance of GSC RAKE receivers over rayleigh fading channel
(
IEEE
, 2011 , Article)
Spread spectrum receivers with generalized selection combining (GSC) RAKE reception were proposed and have been studied as alternatives to the classical two fundamental schemes: maximal ratio combining and selection combining ...
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 ...
Exact closed form expressions for outage probability of GSC receivers over Rayleigh fading channel subject to self-interference
(
IEEE
, 2010 , Conference Paper)
Previous work on performance analyses of generalized selection combining (GSC) RAKE receivers based on the signal to noise ratio focused on the development of methodologies to derive exact closed-form expressions for various ...
Exact capture probability analysis of GSC receivers over Rayleigh fading channel
(
IEEE
, 2010 , Conference Paper)
For third generation systems and ultrawideband systems, RAKE receivers have been introduced due to the advantage of RAKE receivers which is their ability to combine different replicas of the transmitted signal arriving at ...
Performance analysis of best relay selection scheme for fixed gain cooperative networks in non-identical Nakagami-m channels
(
IEEE
, 2010 , Conference Paper)
Selecting the best relay among all the relays ready to cooperate saves system resources and utilizes the available bandwidth more efficiently compared to the regular all-relay cooperation. This scheme also achieves the ...
Performance Analysis of Amplify-and-Forward Hybrid Satellite-Terrestrial Networks with Cochannel Interference
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this paper, we consider an amplify-and-forward hybrid satellite-terrestrial co-operative network in the presence of cochannel interference (CCI). More specifically, we assume that both the satellite-destination and the ...
Precoding-Aided Spatial Modulation for the Wiretap Channel with Relay Selection and Cooperative Jamming
(
Hindawi Limited
, 2018 , Article)
We propose in this paper a physical-layer security (PLS) scheme for dual-hop cooperative networks in an effort to enhance the communications secrecy. The underlying model comprises a transmitting node (Alice), a legitimate ...
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 of Mixed RF/FSO with Variable Gain over Generalized Atmospheric Turbulence Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this paper, we consider a free-space optical (FSO) communication scheme with the help of a variable gain relay where the links from the source to the relay are radio-frequency (RF) links while the links between the relay ...
