Average outage duration of multihop communication systems with regenerative relays
(
IEEE
, 2005 , Article)
Closed-form expressions for the average outage duration (AOD) of multihop regenerative communication systems over generalized fading channels are presented. Both noise-limited and interference-limited systems are studied. ...
I/Q imbalance and loop-back self interference effects in full-duplex OFDM DF relays
(
IEEE
, 2015 , Conference Paper)
We analyze the outage probability of dual-hop full-duplex decode-and-forward relaying for an orthogonal frequency division multiplexing system in the presence of I/Q imbalance. We derive accurate analytical approximations ...
A Deep Reinforcement Learning Framework for Data Compression in Uplink NOMA-SWIPT Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
<comment< Non-orthogonal multiple access (NOMA) shall play an important role in the current and foreseeable design of 5G and beyond networks. NOMA allows multiple users to share the same time-frequency ...
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) ...
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 ...
Outage performance of incremental relaying networks with OFDM subcarriers mapping schemes
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
The scarcity of radio resources coupled with the high data rate demands in the last few years, induced incremental relaying techniques one of the most promising technologies. This is simply because it allows reaping spatial ...
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 ...
Performances analysis of SEC based transmit diversity systems with MRC receivers
(
IEEE
, 2012 , Conference Paper)
Switch and Examine combining (SEC) diversity scheme is one of the simplest yet efficient diversity schemes. Earlier in [1] and [2], we proposed sequential power loading algorithm to reduce the average power used at the ...
Lifetime maximization with predictive power management in selective relay networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2009 , Conference Paper)
A diversity scheme which exploits the existence of a source-destination path to improve the lifetime and outage probability of a wireless selective relay network with Amplifyand-Forward (AF) relays is proposed and studied. ...
Lifetime maximization for greedy selective relay strategies
(2009 , Conference Paper)
In this paper we propose a new algorithm for selective relay strategies with Amplify-and-Forward (AF) relays which improves the relay network lifetime. The lifetime of the relay network is defined as the maximum number of ...
