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 ...
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 ...
A USRP-based experimental testbed for OFDM systems impaired by I/Q imbalance
(
IEEE
, 2013 , Conference Paper)
In this paper, an experimental testbed for packet based OFDM systems is proposed using USRP RF front-ends. I/Q imbalance estimation and compensation algorithms are implemented at the receiver by manually injecting I/Q ...
Digital baseband compensation of frequency-dependent joint TX/RX I/Q imbalance in beamforming MIMO 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 beamforming MIMO-OFDM systems. We derive the throughput-maximizing transmit/receive ...
SINR analysis for beamforming OFDM systems under joint transmit-receive I/Q imbalance
(
IEEE
, 2012 , Conference Paper)
In this paper, we derive an analytical expression for the subcarrier average SINR of a beamforming OFDM system in the presence of joint transmit-receive I/Q imbalance. The derived expression quantifies the impact of the ...
Hybrid thin-films of graphene materials and metallic nanowires for next generation transparent electrodes
(
Optics InfoBase
, 2013 , Conference Paper)
We report advances in the fabrication and characterization of transparent conductive electrodes based on thin-films of metallic nanowires (copper and silver) encapsulated with graphene, graphene oxide, and reduced graphene ...
A low power temperature sensor based on a voltage to time converter cell
(
IEEE
, 2013 , Conference Paper)
In this paper we propose a temperature sensor, based on a voltage to time converter cell (VTC). A VTC is frequently employed in time to digital converters for generating a delay that is proportional to the input voltage. ...
Angular position measurement using resolvers together with a robust linearization technique
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Resolvers are used for both absolute angular and linear position sensing. A robust amplitude to phase converter is described for the determination of position from the sine and cosine output signals of the resolver. The ...
A low power oscillator based temperature sensor for RFID applications
(
IEEE Computer Society
, 2013 , Conference Paper)
In this paper we present a temperature sensor based on a ring oscillator. The ring oscillator uses the CMOS thyristor delay element and has an extremely low power consumption of about 47nW at room temperature with a supply ...
