A sparsity-aware cooperative protocol for cognitive radio networks with energy-harvesting primary user
(
IEEE
, 2015 , Conference Paper)
We consider a cognitive setting composed of multiple primary frequency bands each of which consists of a limited-battery energy-harvesting primary user and a secondary user. The primary user is equipped with a limited-capacity ...
Enhanced Alamouti decoding scheme for DVB-T2 systems in SFN channels
(
IEEE
, 2011 , Conference Paper)
The standard Alamouti space-frequency block code (SFBC) suffers from performance degradation when used over highly frequency-selective channels because the channel frequency response is not necessarily flat over the Alamouti ...
Estimation of highly selective channels for downlink LTE system by a robust neural network
(
IEEE
, 2010 , Conference Paper)
In this paper we propose a robust channel estimator for Long Term Evolution (LTE) downlink highly selective using neural network. This method uses the information provided by the reference signals to estimate the total ...
Cloud-Ready Biometric System for Mobile Security Access
(
Springer
, 2012 , Conference Paper)
In this contribution, we introduce an application that allows a mobile phone to be used as a biometric-capture device for secure access to the cloud. In this application, the biometric capture and recognition are performed ...
On quantized compressed sensing with saturated measurements via greedy pursuit
(
IEEE
, 2015 , Conference Paper)
We consider the problem of signal recovery under a sparsity prior, from multi-bit quantized compressed measurements. Recently, it has been shown that allowing a small fraction of the quantized measurements to saturate, ...
On I/Q imbalance effects in full-duplex OFDM decode-and-forward relays
(
IEEE
, 2014 , 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 survey on data center network topologies
(
Springer
, 2018 , Conference Paper)
Data centers are the infrastructures that support the cloud computing services. So, their topologies have an important role on controlling the performance of these services. Designing an efficient topology with a high ...
Sparsity-Aware multiple relay selection in large dual-hop decode-And-forward broadband relay networks
(
IEEE
, 2016 , Conference Paper)
In this paper, three novel techniques are proposed and investigated for multiple relay selection in dual hop OFDM networks. These techniques are based on the exploitation of sparse signal recovery theory and on carefully-designed ...
ScalNet: A novel network architecture for data centers
(
IEEE
, 2015 , Conference Paper)
This paper presents the design, implementation and evaluation of ScalNet, novel network architecture for data centers. ScalNet is a cost-effective, high- performance and scalable interconnect with almost flat architecture. ...
Cloud-based mobile system for biometrics authentication
(
IEEE
, 2013 , Conference Paper)
This paper introduces a new framework to perform handwritten password authentication as an Internet service based on the cloud computing technology. Using the proposed cloud-based authentication platform, we would be able ...
