On the delay of finite buffered multi-hop relay wireless internet of things
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
The evolution of Internet of Things (IoT) as a new application in wireless networks mandates the utilization of wireless cooperative relaying to overcome the energy limitations of IoT devices. Multi-hop relaying is a ...
Diversity-multiplexing tradeoff for log-normal fading channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Although there has been a growing interest on the study of diversity-multiplexing tradeoff (DMT), the existing works are mostly restricted to the outcomes reported for Rayleigh, Rician, and Nakagami fading channels. In ...
Interference management schemes for multi-user cooperative wireless networks
(
John Wiley and Sons Ltd
, 2016 , Article)
Cooperative communication is a promising technique for future wireless networks. It can be used in improving communication reliability and enhancing spectrum efficiency by using the broadcast nature of radio communication ...
Prior zero forcing for cognitive relaying
(
IEEE
, 2013 , Article)
Relaying primary signals by cognitive base-stations (CBSs) can help the primary system and thus win CBSs a higher chance to transmit their own signals. For this purpose, conventional zero-forcing (CZF) beamforming is a ...
Novel selective OFDM-based cooperative techniques for multi-hop systems
(
Elsevier B.V.
, 2015 , Article)
In multi-hop systems, the theoretical outage probabilities and diversity orders of novel Orthogonal Frequency Division Multiplexing (OFDM) based Decode and Forward (DF) cooperative techniques are derived for different ...
Modeling and analysis of HetNet interference using Poisson Cluster Processes
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Future mobile networks are converging towards being heterogeneous, owing to the co-existence of multi-tier networks within the same geographical area, including macro, pico- and femto-cells. The deployment of such networks ...
Joint hierarchical modulation and network coding for two way relay networks
(
IEEE
, 2012 , Conference Paper)
The performance of a joint Hierarchical Modulation (HM) and Network Coding (NC) scheme for two way relay networks is introduced and evaluated in this paper. The proposed scheme uses selective relaying based on a signal-to-noise ...
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 ...
Adaptive network coding for spectrum sharing systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose an adaptive network coding scheme for cognitive relay networks comprising multiple secondary sources communicating with a common destination in the presence of multiple primary users. Conventional ...
