Theoretical accuracy analysis of indoor visible light communication positioning system based on time-of-arrival
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, an improved channel model and estimation for positioning in indoor environments using the visible light is presented. For positioning, the specific propagation and indoor channel model for visible light is ...
Secure robust collaborative spectrum sensing in the presence of smart attackers
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, collaborative spectrum sensing to detect random signals corrupted by Gaussian noise in the presence of smart attackers is studied. Unlike to the most of related works, we consider a blind attacker detection ...
On the degrees of freedom region of the M x N Interference Channel
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, the K-user MIMO interference channel is considered. The asymmetric DoF region for the channel is studied. The asymmetric DoF represent the set of all achievable DoF combinations {d1, d2,..., dK}. For the ...
Optimization of probability of error in collaborative spectrum sensing of time-limited cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
We study the probability of error optimization problem in collaborative spectrum sensing (CSS) with limited time resources in cognitive radio (CR) networks. The frame structures for sensing and data transmission, if the ...
Performance of eigenvalue based spectrum sensing in full-duplex cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Spectrum sensing is a key component in any cognitive radio network. Recently full-duplex communication, i.e., the ability to transmit and receive at the same time at the same frequency, has become feasible. Residual self ...
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 ...
Optimal power allocation in dispersed cognitive radio systems with carrier aggregation
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we investigate the optimal power allocation problem in dispersed cognitive radios with carrier aggregation. To this end, we model the carrier aggregation using an i - th frequency diversity policy, wherein ...
Performance of non-coherent decode-and-forward relaying over time-varying fading channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Performance analysis of selection combining (SC) for decode-and-forward (DF) relaying in case of general time-varying Rayleigh fading channels is investigated. While auto-regressive (AR) time series model is applied in ...
Impact of stochastic RF energy harvesting relay on wireless point-to-point network
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we study a general practical stochastic energy harvesting (EH) model where in, an EH relay is able to harvest energy from the radio frequency (RF) radiation in a super capacitor. The different aspects of ...
