Estimating the number of sources in white Gaussian noise: Simple eigenvalues based approaches
(
Institution of Engineering and Technology
, 2017 , Article)
Estimating the number of sources is a key task in many array signal processing applications. Conventional algorithms such as Akaike's information criterion (AIC) and minimum description length (MDL) suffer from underestimation ...
On the Achievable Rates of OFDM with Common Phase Error Compensation in Phase Noise Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
This paper considers the problem of analytically assessing the maximum achievable rates (capacity) of orthogonal frequency division multiplexing (OFDM) transmissions when the receiver, for complexity reasons, only accounts ...
Dynamic interference-limited relay sharing in cognitive radio networks by using hierarchical modulation
(
Institution of Engineering and Technology
, 2017 , Article)
Sharing a relay in cognitive radio (CR) networks in order to enhance the secondary user's (SU's) performance in an interference-limited scheme is investigated. It is assumed, by utilising hierarchical modulation, a shared ...
Swinging with the Jet Set: Analysis of Electromagnetic Fields Inside Jet Engines - From Numerical and Experimental Analysis to Statistical Analysis
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Analyzing electromagnetic propagation inside jet engine turbines is a challenging and important research topic due to its potential applications in both civil and military fields. Electromagnetic modeling of such complex ...
On the coexistence of a primary user with an energy harvesting secondary user: A case of cognitive cooperation
(
John Wiley and Sons Ltd
, 2016 , Article)
In this paper, we consider a cognitive scenario where an energy harvesting secondary user shares the spectrum with a primary user. The secondary source helps the primary source in delivering its undelivered packets during ...
Optimized Error Probability for Weighted Collaborative Spectrum Sensing in Time-and Energy-Limited Cognitive Radio Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
In this paper, a collaborative energy-harvesting cognitive radio (CR) network is considered such that the transmitter of the secondary user (SU) is allowed to harvest signal energy of the primary user (PU) when the presence ...
Relay-Assisted Primary and Secondary Transmissions in Cognitive Radio Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
We assume a set of cognitive relay nodes that assists both primary and secondary transmissions in a time-slotted cognitive radio networks. To regulate the channel access of the various nodes in the network, we propose an ...
Throughput of a cooperative energy harvesting secondary user in cognitive radio networks
(
Wiley Blackwell
, 2016 , Article)
This paper investigates the maximum throughput of a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU). The SU is assumed to be an energy harvesting node, which harvests energy packets from the ...
On the Higher Order Statistics of the Channel Capacity in Dispersed Spectrum Cognitive Radio Systems Over Generalized Fading Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
This work is devoted to the study of dispersed spectrum cognitive radio (CR) systems over independent and nonidentically distributed (i.n.i.d.) generalized fading channels. More specifically, this is performed in terms of ...
On dual peak detection UWB receivers in noise and interference dominated environments
(
Elsevier GmbH
, 2016 , Article)
We propose the use of a non-coherent dual peak detection architecture for ultra wideband (UWB) receivers. To benchmark our proposed architecture, the performance of non-coherent UWB receivers based on single peak, dual ...
