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 ...

Multitone jamming of FH/BFSK in Rician channels

IEEE Transactions on Communications, 1999
A new bit error rate (BER) expression for a noncoherent frequency-hopped binary-frequency-shift-keying (FH/BFSK) receiver in Rician channels, subjected to independent multitone and wideband noise interference, is derived. Unlike previously published analyzes, we combine the signal and jammer multipath components, the additive white Gaussian noise (AWGN)

Outage Analysis for MIMO Rician Channels and Channels with Partial CSI

2006 IEEE International Symposium on Information Theory, 2006
We analyze the outage performance and diversity-multiplexing tradeoff (DMT), originally introduced by Zheng and Tse, for multiple antenna Rician channels or channels with partial channel state information at the transmitter (CSIT). The asymptotic behaviors of the outage are analyzed in the limit of high signal-to-noise ratio (SNR).

Performance of decorrelating receivers in multipath Rician fading channels

IEEE Transactions on Wireless Communications, 2005
This letter focuses on the performance analysis of the decorrelating receiver in multipath Rician faded CDMA channels. M-ary QAM scheme is employed to improve the spectral efficiency. Approximate expressions are first derived for the two performance indexes: the average symbol error rate (SER) and the average bit error rate (BER) when the decorrelating-

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 ...

On the statistical properties of Rician-K channels

Proceedings of 2012 2nd International Conference on Computer Science and Network Technology, 2012
This paper deals with the statistical properties of the Rician-K channels, the product of a Rician process and a K process. From the moments characteristics of the Rician-K process we estimated the parameters of the Rician-K channels. Then, we derived the second-order fading statistics of the Rician-K channels, known as level crossing rate (LCR) and ...

Nonlinear equalization for Rician multipath fading channel

2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2004
We present a nonlinear equalization scheme for a Rician multipath fading channel - a fuzzy logic-based approach. We show that each channel state of a multipath Rician channel follows a Gaussian distribution, which means a Bayesian equalization can be implemented.
