Probability of Strictly Positive Secrecy Capacity of the Rician-Rician Fading Channel

IEEE Wireless Communications Letters, 2013
Communication security is critical in the marine environment as information may be transmitted over large open areas like high seas. In this letter, an analysis is conducted on the probability of secrecy capacity for wireless communications over the Rician fading channels. In particular, a closed-form expression for the probability of strictly positive

Statistical simulation models for Rayleigh and Rician fading [PDF]

IEEE International Conference on Communications, 2003. ICC '03., 2004
New simulation models are proposed for Rayleigh and Rician fading channels. First, the statistical properties of Clarke's fading model with a finite number of sinusoids are analyzed. An improved Clarke's model is then proposed for the simulation of Rayleigh fading channels.

Distributions of Multivariate Correlated Rayleigh and Rician Fading

IEEE Transactions on Information Theory, 2017
Single-integral expressions for cumulative distribution functions of multivariate correlated Rayleigh and Rician fading are studied. Mathematical mistakes in the literature are identified and corrected. Corrections are cross-verified against well-known findings in the literature, which can be employed to advance further theoretical developments for ...

SOP under dual correlated Rician fading

2018 24th Asia-Pacific Conference on Communications (APCC), 2018
Under dual correlated Rician fading and unknown wiretapper’s channel state information, secrecy outage probability (SOP) is theoretically studied for the first time in this paper. The signal-to-noise ratio probability density function of bivariate correlated Rician fading is derived. Using an infinite-summation form for the modified Bessel functions of

Outage Prediction for URLLC in Rician Fading

2021 IEEE 32nd Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2021
By scheduling users to resources that are operational rather than on a best effort basis, the overall resource consumption of ultra-reliable low-latency communications (URLLC) can be reduced while maintaining a desired quality of service (QoS).

Microdiversity on rician fading channels

IEEE Transactions on Communications, 1994
formats, coherent phase shift keying (CPSK) and -noncoherent frequency shift keying (NCFSK). Results using both maximal ratio combining (MRC) and selection diversity combining (SC) are presented for comparison. Our results show that from a feasibility and practical tradeoffs point of view, the performance of an EG combiner may be as good as that of a ...

The Fading Number of a Multiple-Access Rician Fading Channel

IEEE Transactions on Information Theory, 2009
The fading number of a noncoherent two-user Ri-cian fading channel is derived. The fading number is the second term in the high-SNR expansion of the sum-rate capacity of this multiple-access channel. It is shown that the fading number is identical to the fading number of the single-user Rician fading channel that is obtained when the user seeing the ...

Differential detection of GMSK in Rician fading

IEEE Transactions on Communications, 1994
The symbol error probability of Gaussian MSK using differential detection in a Rician fast fading channel is investigated. In the analysis, the effect of the infinite sequence of intersymbol interference inherent in this modulation is included exactly, and the performance can be evaluated at narrow shaping bandwidths where the intersymbol interference ...
