Analysis of heterogeneous cellular networks interference with biased cell association using Poisson cluster processes
(
IEEE Computer Society
, 2014 , Conference Paper)
Heterogeneous cellular networks (HetNets) achieve high data rates and coverage gains by distributing small cells over macro-cells based on random user demand. Recently, a novel approach to use stochastic geometry for ...
Joint optimal threshold-based relaying and ml detection in network-coded two-way relay channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2012 , Article)
In this paper, we address the problem of joint optimal threshold-based relaying and maximum likelihood (ML) detection in network-coded cooperative systems. The purpose of using threshold-based relaying is to circumvent the ...
On hierarchical network coding versus opportunistic user selection for two-way relay channels with asymmetric data rates
(
IEEE
, 2013 , Article)
We address in this paper the challenge of coping with asymmetric data rates in two-way relay channels. We consider a relay network comprising two sources and one relay. The sources communicate at different rates through ...
Cooperative OFDM systems for UWAC with SNR-based relay selection schemes
(
IEEE
, 2012 , Conference Paper)
In this paper, we investigate a multi-carrier multi-relay cooperative system with amplify-and-forward relaying over frequency-selective underwater acoustic channels. Relay selection rules rely on the maximization of ...
Performance analysis of relay assignment schemes for cooperative networks with multiple source-destination pairs
(
IEEE
, 2012 , Article)
In this paper, we consider two relay assignment schemes for cooperative networks comprising multiple source-destination pairs. Both schemes are based on the max-min criterion and aim at achieving the maximum spatial diversity ...
Effective area spectral efficiency for wireless communication networks with interference management
(
Springer International Publishing
, 2015 , Article)
In this paper, we introduce a new metric, namely, effective area spectral efficiency (EASE), to quantify the spectral efficiency as well as the spatial properties of point-to-point transmission systems and decode and forward ...
Novel cooperative communication schemes with interference management for multi-user wireless networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
Cooperative communication is a promising technique for future wireless networks. It can be used in improving communication reliability, and enhancing power and spectrum efficiency. However, its performance gain degrades ...
Joint optimal threshold-based relaying and ML detection in cooperative networks
(
IEEE
, 2012 , Article)
This paper proposes two detection schemes for cooperative networks comprising a source, a relay and a destination. The relay is assumed to operate in a half-duplex mode and it employs decode-and-forward (DF) relaying. The ...
Stability and delay analysis for cooperative relaying with multi-access transmission
(
Springer Verlag
, 2015 , Conference Paper)
We consider a cooperative relaying system with two source terminals, one full duplex relay, and a common destination. Each terminal has a local traffic queue while the relay has two relaying queues to store the relayed ...
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 ...
