Energy-cost-distortion optimization for delay-sensitive M-health applications
(
IEEE Computer Society
, 2015 , Conference Paper)
Mobile-health (m-health) systems leverage wireless and mobile communication technologies to promote new ways to acquire, process, transport, and secure the raw and processed medical data to provide the scalability needed ...
On the group proportional fairness of frequency domain resource allocation in L-SC-FDMA based LTE uplink
(
IEEE
, 2010 , Conference Paper)
Localized single carrier frequency division multiple access (L-SC-FDMA) has been selected as the uplink transmission scheme in 3GPP Long Term Evolution (LTE) due to its low Peak to Average Power Ratio (PAPR) over OFDMA in ...
A cooperative Q-learning approach for distributed resource allocation in multi-user femtocell networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
This paper studies distributed interference management for femtocells that share the same frequency band with macrocells. We propose a multi-agent learning technique based on distributed Q-learning, called subcarrier-based ...
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 ...
Modeling Heterogeneous Cellular Networks Interference Using Poisson Cluster Processes
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
Future mobile networks are converging toward heterogeneous multitier networks, where macro-, pico-, and femto-cells are randomly deployed based on user demand. A popular approach for analyzing heterogeneous networks (HetNets) ...
Optimal power consumption based on new power spectral efficiency metric for wireless cellular networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we introduce a new power spectral efficiency (PSE) metric, to quantify the spectral efficiency and the total required power to cover a certain area with a predefined received signal quality. This metric ...
Cooperative communications scheme with interference management under ICI for OFDM LTE-A systems
(
IEEE Computer Society
, 2013 , Conference Paper)
In long term evolution (LTE) systems, the achievable cell spectral efficiency is often limited by the inter carrier interference (ICI) or coverage shortage of base stations. Hence, in LTE-Advanced, cooperative communication ...
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 ...
Outage performance of multi-hop hybrid FSO/RF communication systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, five scenarios are considered for the realization of a multi-hop hybrid free-space optical/radio frequency (FSO/RF) communication system with decode-and-forward (DF) relaying, and analytical outage probability ...
