Relay selection schemes to minimise outage in wireless powered communication networks
(
Institution of Engineering and Technology
, 2016 , Article)
In this study, the authors discuss relay selection schemes with the objective to minimise outage probability for a network consisting of a single source, multiple relays and a single destination. The relays are powered by ...
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 ...
Cognitive Radio Networks with Probabilistic Relaying: Stable Throughput and Delay Tradeoffs
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
This paper studies fundamental throughput and delay tradeoffs in cognitive radio systems with cooperative secondary users. We focus on randomized cooperative policies, whereby the secondary user (SU) serves either its own ...
3-D Stochastic Geometry-based Modeling and Performance Analysis of Efficient Security Enhancement scheme for IoT Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
Internet of Things (IoT) systems are becoming core building blocks for different services and applications supporting every day’s life. The heterogeneous nature of IoT devices and the complex use scenarios make it ...
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 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) ...
Joint statistics of partial sums of ordered exponential variates and performance of GSC RAKE receivers over rayleigh fading channel
(
IEEE
, 2011 , Article)
Spread spectrum receivers with generalized selection combining (GSC) RAKE reception were proposed and have been studied as alternatives to the classical two fundamental schemes: maximal ratio combining and selection combining ...
Optimal power allocation for relayed transmissions over Rayleigh-fading channels
(
IEEE
, 2004 , Article)
Relayed transmission is a way to attain broader coverage by splitting the communication link from the source to the destination into several shorter links/hops. One of the main advantages of this communication technique ...
A performance study of dual-hop transmissions with fixed gain relays
(
IEEE
, 2004 , Article)
This letter presents a study on the end-to-end performance of dual-hop wireless communication systems equipped with nonregenerative fixed gain relays and operating over flat Rayleigh-fading channels. More specifically, it ...
A promising non-orthogonal multiple access based networking architecture: Motivation, conception, and evolution
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Since it can offer higher spectral efficiency by granting the served data to share the same spectrum resource synchronously, NOMA is considered as a bright multiple access technique for future wireless networks. Accommodating ...
