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 ...
HVDC shunt tap based on series-input parallel-output DC-AC multi-module VSCs with DC voltages balancing
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Conventionally, tapping-off a small amount of power from an HVDC transmission line to a three-phase local network can be achieved using a DC-to-AC voltage source converter (VSC) followed by a step down transformer. In order ...
Embedded gateway services for Internet of Things applications in ubiquitous healthcare
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
The continuous advancement in computer and communication technologies has made personalized healthcare monitoring a rapidly growing area of interest. New features and services are envisaged, raising users' expectations in ...
On the correlation analysis of electric field inside jet engine
(
IEEE
, 2014 , Conference Paper)
A Simple channel modeling method based on correlation analysis of the electric field inside jet engine is presented. The analysis of the statistical propagation characteristics of electromagnetic field inside harsh jet ...
Hybrid underlay/overlay cognitive radio system with hierarchical modulation in the presence of channel estimation error
(
IEEE
, 2014 , Conference Paper)
In this paper, we study the performance of hybrid cognitive radio (CR) system in the presence of channel estimation error (CER) in terms of bit-error-probability (BEP) and outage probability. We assume simultaneous switching ...
Exact average OFDM subcarrier SINR analysis under joint transmit-receive I/Q imbalance
(
IEEE
, 2014 , Article)
The subcarrier signal-to-interference-plus-noise ratio (SINR) expression for orthogonal frequency-division multiplexing (OFDM) systems impaired by in-phase/quadrature (I/Q) imbalance is a ratio of correlated random variables. ...
Maximum throughput of a secondary user cooperating with an energy-aware primary user
(
IEEE Computer Society
, 2014 , Conference Paper)
This paper proposes a cooperation protocol between a secondary user (SU) and a primary user (PU) which dedicates a free frequency subband for the SU if cooperation results in energy saving. Time is slotted and users are ...
Relay assignment in multiple source-destination cooperative networks with limited feedback
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
We consider in this paper relay assignment for cooperative systems with mutiple source-destination pairs. The objective here is to assign relays to the source-destination pairs in such a way that all pairs achieve the ...
Multiple sensor fault diagnosis by evolving data-driven approach
(
Elsevier Inc.
, 2014 , Article)
Sensors are indispensable components of modern plants and processes and their reliability is vital to ensure reliable and safe operation of complex systems. In this paper, the problem of design and development of a data-driven ...
