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.

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 ...

Outage Probability of Rician Fading Relay Channels

MILCOM 2006, 2006
In this paper, we consider the decode-and-forward (DF) relay network system over Rician fading channels. We derive an analytical expression for the outage probability of the highest achievable information rate of the system, which can be evaluated by employing standard numerical techniques. We also obtain some simple but tight lower and upper bounds on

Blind Modulation Classification for Rician Aeronautical Channels

2014 IEEE Military Communications Conference, 2014
Blind modulation classification (BMC) is one of the most important functions for modern electronic warfare. The aim of BMC is to identify the modulation type of transmitted signals by using only the samples of received signals without prior knowledge of transmitted signals.

On the Outage Probability Optimization in MISO Rician Channels

2009 IEEE International Conference on Wireless and Mobile Computing, Networking and Communications, 2009
We address the optimization issue of the outage probability in Rician block fading channels with $N$ transmit antennas and $1$ receive antenna. It is already known that the eigenvectors of the covariance matrix of the transmit signal that minimizes the outage probability are the normalized mean vector of the Rician channel and $N-1$ orthonormal vectors

Turbo code performance on Rician fading channels

1999 IEEE International Conference on Communications (Cat. No. 99CH36311), 2003
The performance of turbo codes on frequency non-selective slow Rician fading channels is considered. The analytical average upper bounds of turbo code performance over the channels with independent fading are derived. Furthermore, we developed a decoding metric for fading channels and log-likelihood ratios and extrinsic information for maximum a ...
