Cooperative access schemes for efficient SWIPT transmissions in cognitive radio networks
(
IEEE
, 2015 , Conference Paper)
We investigate joint information and energy cooperative schemes in a slotted-time cognitive radio network with a primary transmitter-receiver pair and a set of secondary transmitter-receiver pairs. The primary transmitter ...
I/Q imbalance and loop-back self interference effects in full-duplex OFDM DF relays
(
IEEE
, 2015 , 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 ...
Exploiting sparsity of relay-assisted cognitive radio networks
(
IEEE
, 2015 , Conference Paper)
We propose a novel protocol for secondary users based on compressive sensing principles. The secondary user assigned to one of the primary frequency bands is aided by a set of nearby secondary users, which we refer to as ...
Sensor network architecture for deployment over low voltage powerlines
(
IEEE
, 2010 , Conference Paper)
This paper presents the design and implementation of an efficient sensor network (SN) over standard powerlines. As an application of the proposed SN, a home security and surveillance system was designed and implemented. ...
Decentralized multiuser diversity with opportunistic packet transmission in MIMO wireless sensor networks
(
Elsevier
, 2013 , Article)
In this study, we consider a single-hop wireless sensor network where both the sensor nodes and the controller node have multiple antennas. We focus on single beam opportunistic communication and propose a threshold-based ...
A threshold-based opportunistic MAC protocol for MIMO wireless sensor networks
(
IEEE
, 2012 , Conference Paper)
In this paper, we consider a single-hop wireless sensor network where both the sensor nodes and the controller node have multiple antennas. We focus on single beam opportunistic communication and propose a threshold-based ...
Convolutional Neural Networks for patient-specific ECG classification
(
IEEE
, 2015 , Conference Paper)
We propose a fast and accurate patient-specific electrocardiogram (ECG) classification and monitoring system using an adaptive implementation of 1D Convolutional Neural Networks (CNNs) that can fuse feature extraction and ...
I/Q imbalance in multiple beamforming {OFDM} transceivers: SINR analysis and digital baseband compensation
(
IEEE
, 2013 , Article)
In this paper, we start by investigating the impact of joint transmit-receive I/Q imbalance on the performance of direct-conversion beamforming OFDM transceivers. We derive a new analytical expression for the average ...
Modelling and compensation of frequency-dependent I/Q imbalance in multiple beamforming OFDM transceivers
(
IEEE
, 2012 , Conference Paper)
In this paper, we investigate the effects of asymmetric frequency-dependent joint transmit-receive I/Q imbalance on the performance of multiple beamforming MIMO OFDM systems. We derive the throughput-maximizing TX/RX ...
WFlatnet: Introducing wireless in flatnet data center network
(
IEEE
, 2015 , Conference Paper)
The basic challenge of data centers is how to interconnect a huge number of servers while guaranteeing the performance of the network. Flatnet is a promising data center architecture that has proved its efficiency to connect ...
