Capacity of MRC on Correlated Rician Fading Channels [PDF]

IEEE Transactions on Communications, 2008
A new exact explicit expression is derived for the ergodic capacity of maximal ratio combining (MRC) schemes over arbitrarily correlated Rician fading channels. This is used to study the effects of channel correlation on the ergodic capacity. Numerical results reveal that both the phase and the magnitude of correlation have an impact on the ergodic ...

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

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 ...

A BER Analysis of NOMA on Rician Fading Channels

2020 IEEE Latin-American Conference on Communications (LATINCOM), 2020
Non-Orthogonal Multiple Access (NOMA) has been a hot research topic over the past years. The general trend in the NOMA literature is the so-called Power-Domain NOMA (PD-NOMA), which requires a strong power imbalance at the receiver between the superposed signals.

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 ...

Convolutional Code Performance in the Rician Fading Channel

IEEE Transactions on Communications, 1976
The performance of short constraint length convolutional codes in conjunction with binary phase-shift keyed (BPSK) modulation and Viterbi maximum likelihood decoding on the classical Rician fading channel is examined in detail. Primary interest is in the bit error probability performance as a function of E_{b}/N_{0} parameterized by the fading channel ...

MIMO capacity results for Rician fading channels

GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004
The capacity of a multiple antenna system in Rician fading is considered under the assumption that channel state information (CSI) is available only at the receiver and that the transmitter has knowledge of the statistical properties of the fading process though not the instantaneous CSI.

Approximation to the Capacity of Rician Fading MIMO Channels

VTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009
In this paper, the capacity of multiple-input multiple-output (MIMO) systems over a Rician fading channel is evaluated. We show that the capacity of MIMO Rician channels can be well approximated by that of correlated MIMO Rayleigh channels. We take the Rician channel with rank-1 mean matrices as an example, the asymptotic capacities at low and high ...
