Sensors, 2015 Recently, a novel resource-efficient technique for the reporting channel transmissions in cooperative spectrum sensing was proposed. In this technique, secondary users are allowed to simultaneously send their local decisions to the fusion center, saving ...

IEEE Access, 2018 In this paper, we investigate the statistical properties of double Hoyt fading channels, where the overall received signal is determined by the product of two statistically independent but not necessarily identically distributed single Hoyt processes ...

Channel-based spoofing detection in frequency-selective rayleigh channels [PDF]
IEEE Transactions on Wireless Communications, 2009 The radio channel response decorrelates rapidly as the transmitter changes location in an environment with rich scatterers and reflectors. Based on this fact, a channel-based authentication scheme was previously proposed to discriminate between transmitters at different locations, and thus to detect spoofing attacks in wireless networks. In this paper,

Differential Amplify-and-Forward Relaying in Time-Varying Rayleigh Fading Channels [PDF]
, 2013 This paper considers the performance of differential amplify-and-forward (D-AF) relaying over time-varying Rayleigh fading channels. Using the auto-regressive time-series model to characterize the time-varying nature of the wireless channels, new weights

Extending and Merging the Purple Crow Lidar Temperature Climatologies Using the Inversion Method
EPJ Web of Conferences, 2016 Rayleigh and Raman scatter measurements from The University of Western Ontario Purple Crow Lidar (PCL) have been used to develop temperature climatologies for the stratosphere, mesosphere, and thermosphere using data from 1994 to 2013 (Rayleigh system ...

The Effect of Macrodiversity on the Performance of Maximal Ratio Combining in Flat Rayleigh Fading
, 2013 The performance of maximal ratio combining (MRC) in Rayleigh channels with co-channel interference (CCI) is well-known for receive arrays which are co-located.

Grassmannian Beamforming for MIMO Amplify-and-Forward Relaying [PDF]
, 2007 In this paper, we derive the optimal transmitter/ receiver beamforming vectors and relay weighting matrix for the multiple-input multiple-output amplify-and-forward relay channel. The analysis is accomplished in two steps.

On multilevel coded MPSK for the Rayleigh fading channel [PDF]
Proceedings of PIMRC '96 - 7th International Symposium on Personal, Indoor, and Mobile Communications, 1999 We derive a new upper bound on the pairwise error probability for MPSK sequences over the Rayleigh fading channel when channel state information (CSI) is not available. This is obtained by adding weight factors in calculating the symbol metrics. Simulation shows that the weight factors which optimize the upper bound are likely to optimize the error ...
