On capacity of Rician MIMO channels

12th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications. PIMRC 2001. Proceedings (Cat. No.01TH8598), 2002
Use of antenna arrays at both sides of the communication link can result in high channel capacities provided that the propagation medium is rich scattering. Previous studies on MIMO wireless structures have mostly considered Rayleigh fading conditions. Here a study is made on the capacity of Rician channels; it is shown that depending on the number of ...

Co-channel interference analysis of shadowed Rician channels

IEEE Communications Letters, 1998
This paper presents an exact analysis of co-channel interference (CCI) in a shadowed-Nakagami (desired)/shadowed-Rician (interfering) channel. Because a Rician distribution can be closely approximated by a Nakagami distribution (Nakagami 1960), the proposed analysis can be viewed as a close approximation of a shadowed-Rician (desired)/shadowed-Rician ...

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 ...

Novel Sum-of-Sinusoids Simulation Models for Rayleigh and Rician Fading Channels [PDF]

IEEE Transactions on Wireless Communications, 2006
The statistical properties of Clarke\u27s fading model with a finite number of sinusoids are analyzed, and an improved reference model is proposed for the simulation of Rayleigh fading channels.

On the capacity of frequency-flat and frequency-selective Rician MIMO channels with single-ended correlation

IEEE Transactions on Wireless Communications, 2006
This paper considers the ergodic capacity of spatially-correlated Rician MIMO channels. We address the case where the Rician component has a single dominant path and where the correlation occurs at one end of the MIMO link.

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.

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.

Achievable performance over the correlated Rician channel

IEEE Transactions on Communications, 1994
The correlated Rician channel is a useful model for a slowly fading channel, in which the complex fading process is composed of two quadrature Gaussian processes with a given autocorrelation function. For slow fading the correlation between adjacent symbols is relatively high. The authors investigate the achievable error probabilities over the channel,

Optimum Beamforming for Correlated Rician MISO Channels

2011 IEEE 73rd Vehicular Technology Conference (VTC Spring), 2011
In the present work the optimum beamforming problem for correlated Rician MISO channels is solved in the context of a simple one-dimensional optimization problem. Simulations derived for linear equi-spaced arrays compare the capacity performance of the optimum beamformer with different transmission strategies (referred to as Max SNR Beamformer and ...

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 ...
