Exposure assessment to WiFi access points by simulations and measurements
(
IEEE
, 2011 , Conference Paper)
This paper discusses two different approaches to assess exposure to indoor WiFi access points at two different frequency bands: 2.4GHz and 5GHz. The first analyzes the electromagnetic propagation in almost empty environments ...
Advanced experimental setup for the reliability characterization of radio-acoustic sensors in water pipes
(
IEEE
, 2011 , Conference Paper)
The paper presents the design and construction of a test bench for the analysis and certification of radio-acoustic sensors inside conduits filled with liquids. It is a brand new test-set that integrates the capability to ...
On relay assignment in network-coded cooperative systems
(
IEEE
, 2011 , Article)
We consider in this paper relay assignment for cooperative systems with multiple two-way relay channels. The nodes corresponding to one two-way relay channel (henceforth referred to as pair) communicate with each other ...
Threshold-based relaying in coded cooperative networks
(
IEEE
, 2011 , Article)
In cooperative communications, error propagation at the relay nodes degrades the diversity order of the system. To combat that effect, we present a novel technique to control error propagation at the relays, which is ...
Two way opportunistic MAC protocol for Ad Hoc networks
(
IEEE
, 2011 , Conference Paper)
In this paper, network coding is introduced in relay based MAC protocols for bidirectional traffic to evaluate the performance in terms of throughput and energy. The idea of proposed scheme is to use high data rate nodes ...
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 ...
Analysis of cell spectral efficiency of infrastructure relay-enhanced cellular system
(
IEEE
, 2011 , Conference Paper)
In this paper, we investigate the downlink spectral efficiency of infrastructure relay-enhanced cellular systems. In particular, we use the average achieved spectral efficiency at an arbitrary mobile receiver in presence ...
Performance analysis of selective cooperation in underlay cognitive networks over Rayleigh channels
(
IEEE
, 2011 , Conference Paper)
Underlay cognitive networks should follow strict interference thresholds to operate in parallel with primary networks. This constraint limits their transmission power and eventually the area of coverage. Therefore, it is ...
