Probability of Strictly Positive Secrecy Capacity of the Rician-Rician Fading Channel [PDF]
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

Capacity bounds for correlated Rician MIMO channels
IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005 In this paper we derive tight upper and lower bounds on the MIMO capacity in correlated Rician fading channels. We assume that the receiver has perfect knowledge of the channel, and the transmitter has no knowledge (instantaneous or statistical). We examine two common power normalization models, and show how the capacity changes with Rician K-factor ...

Beamforming Capacity Optimization for Rician MIMO Wireless Channels
IEEE Wireless Communications Letters, 2012 The beamformer that maximizes the ergodic beamforming capacity under correlated (or uncorrelated with non-unit covariance matrix) Rician MISO channels can be calculated in the context of a simple one-dimensional optimization problem, according to the solution proposed in [1].

Matched filter bound for multipath Rician-fading channels
IEEE Transactions on Communications, 1998 This paper derives an infinite series and an integral for computing matched filter bounds for binary phase-shift keying (BPSK) communications over a multipath Rician-fading channel of discrete or continuous dispersion. Based on the derived bound we compare intrinsic frequency diversity (IFD) gains for channels of different Rician factors.

Copulas for statistical signal processing (Part I) : extensions and generalization [PDF]
, 2014 Existing works on multivariate distributions mainly focus on limited distribution functions and require that the associated marginal distributions belong to the same family. Although this simplifies problems, it may fail to deal with practical cases when

On the capacity of MIMO Rician broadcast channels [PDF]
2008 IEEE International Symposium on Information Theory, 2008 In this paper, a downlink communication system, in which a base station (BS) equipped with M antennas communicates with N (N Gt 1) single-antenna users, in a Rician fading environment is considered. The asymptotic (in terms of the number of users) sum-rate capacity of the system, as well as the capacity-achieving strategies, are derived.

Location-based beamforming for Rician wiretap channels [PDF]
2016 Australian Communications Theory Workshop (AusCTW), 2016 We propose a location-based beamforming scheme for wiretap channels, where a source communicates with a legitimate receiver in the presence of an eavesdropper. We assume that the source and the eavesdropper are equipped with multiple antennas, while the legitimate receiver is equipped with a single antenna.

Monotonicity Results for Coherent MIMO Rician Channels [PDF]
IEEE Transactions on Information Theory, 2005 The dependence of the Gaussian input information rate on the line-of-sight (LOS) matrix in multiple-input multiple-output coherent Rician fading channels is explored. It is proved that the outage probability and the mutual information induced by a multivariate circularly symmetric Gaussian input with any covariance matrix are monotonic in the LOS ...

Cross-packing lattices for the Rician fading channel [PDF]
2015 IEEE Information Theory Workshop (ITW), 2015 We introduce cross-packing lattices for Rician fading channels, motivated by a geometric interpretation stemming from the pairwise error probability analysis. We approximate the star bodies arising from the pairwise error probability analysis with n-dimensional crosses of radius t, consisting of 2nt + 1 unit cubes, for some positive integer t.
