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 ...
Culture of PC12 neuronal cells in GelMA hydrogel for brain tissue engineering
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Restoration of brain functions following trauma or degenerative neural diseases is considered among the greatest challenges in neurology due to the fact that the central nervous system (CNS) does not regenerate on its own. ...
Dynamic power pricing using distributed resource allocation for large-scale DSA systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose dynamic power pricing for distributed resource allocation in large-scale Dynamic Spectrum Access (DSA) systems. The dynamic power pricing is considered to influence the users' spectrum assignment ...
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 ...
A kernel-based approach to MIMO LPV state-space identification and application to a nonlinear process system
(
Elsevier B.V.
, 2015 , Conference Paper)
This paper first describes the development of a nonparametric identification method for linear parameter-varying (LPV) state-space models and then applies it to a nonlinear process system. The proposed method uses kernel-based ...
Performance analysis of cooperative communication system with feedback delay and channel estimation error
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we investigate the impact of feedback delay and channel estimation error (CEE) on the performance of wireless multi-user decode-and-forward (DF) relay systems in independent and non identically distributed ...
On the design of relay-assisted primary-secondary networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The use of N cognitive relays to assist primary and secondary transmissions in a time-slotted cognitive setting with one primary user (PU) and one secondary user (SU) is investigated. An overlapped spectrum sensing strategy ...
Secret key generation based on AoA estimation for low SNR conditions
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In the context of physical layer security, a physical layer characteristic is used as a common source of randomness to generate the secret key. Therefore an accurate estimation of this characteristic is the core for reliable ...
ECG security identification system on the Zynq SoC platform
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Electrocardiogram (ECG) is one of the most safety-relevant biometrics due to its live indication and the unique specific waveform. This paper presents an approach for a security identification system and its System-on-Chip ...
Web service cost optimization
(
Association for Computing Machinery, Inc
, 2015 , Conference Paper)
Cloud computing has become a major building block for Web applications where the service providers provide the costumers with Web services performing certain tasks so the system developers can use these services instead ...
