Detection of temporally correlated primary user signal with multiple antennas
(
Springer Verlag
, 2015 , Conference Paper)
In this paper, we address the problem of multiple antenna spectrum sensing in cognitive radios (CRs) when the samples of the primary user (PU) signal as well as samples of noise are assumed to be temporally correlated. We ...
Inter-relay interference cancellation for wireless multi-user multi-decode-and-forward relay networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, a cooperative communication scheme with inter-relay interference (IRI) cancellation is proposed for wireless multi-user multi-decode-and-forward (DF) relay networks. The scheme is based on a DF half-duplex ...
Non-uniform quantized distributed sensing in practical wireless rayleigh fading channel
(
Springer Verlag
, 2015 , Conference Paper)
In this paper, we study non-uniform multilevel quantization problem in cognitive radio networks (CRNs). We consider a practical collaborative spectrum sensing (CSS) scenario in which secondary users (SUs) cooperate with ...
Feasibility of air quality monitoring systems based on environmental energy harvesting
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Capillary wireless sensor networks dedicated to air quality monitoring have provided essential information on hazardous air condition, generating early warnings to prevent danger situation for human health. The arising ...
A survey of wireless data center networks
(
IEEE
, 2015 , Conference Paper)
Data centers are becoming more and more popular for a wide variety of applications. However, the efficiency of data centers are restricted by many issues like cabling and maintenance problems in addition to performance ...
On orthogonal band allocation for multiuser multiband cognitive radio networks: Stability analysis
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this work, we study the problem of band allocation of Mi buffered (i.e., with data queues capable of storing incoming traffic packets) secondary users (SUs) to Mp primary frequency bands licensed to (owned by) Mp buffered ...
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 ...
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 ...
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 ...
