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 ...
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 ...
Sparsity-cognizant multiple-access schemes for large wireless networks with node buffers
(
IEEE
, 2015 , Conference Paper)
This paper proposes efficient multiple-access schemes for large wireless networks based on the transmitters' buffer state information and their transceivers' duplex transmission capability. First, we investigate the case ...
Advanced packet scheduling for efficient video support with limited channel feedback on MIMO LTE downlink

Next-generation mobile networks will provide users with high data rates, increased mobility and various services. The initial step made in LTE and LTE-A is adopting the OFDM(A) air interface and utilization of dynamic ...
Sparsifying dictionary analysis for FIR MIMO channel-shortening equalizers
(
IEEE
, 2016 , Conference Paper)
In this paper, we propose a general framework that transforms the problems of designing sparse finite-impulse response channel-shortening equalizers and target impulse response filters for multiple antenna systems into the ...
On the detection and estimation of correlated signal using circular antenna arrays
(
IEEE
, 2011 , Conference Paper)
This paper presents the design and analysis of smart antenna systems used for the detection and estimation of correlated radio signals encountered in multipath environments using circular antenna arrays. The MUSIC algorithm ...
Energy-efficient based on cluster selection and trust management in cooperative spectrum sensing
(
IEEE
, 2016 , Conference Paper)
Cooperative spectrum sensing (CSS) has been proposed as a solution for radio spectrum resources scarcity problem. Clustering technique is introduced to increase the performance of CSS and overcome the shadowing and fading ...
