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 ...
