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-

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.

Rician channel characterization in OFDM systems

2015 23rd Iranian Conference on Electrical Engineering, 2015
Rician model is a stochastic channel model which is used for multipath propagation when line of sight (LOS) signal is much stronger than the other signals received from the other paths. In this paper we focus on Rician model of fading channel in Orthogonal Frequency Division Multiplexing (OFDM) systems and evaluate the effect of LOS signal on channel ...

Capacity estimation of Rician MIMO channels

2004 International Waveform Diversity & Design Conference, 2004
Several analytical and simulation results are available in the literature for the capacity of multiple input multiple output (MIMO) channels in Rayleigh fading. In this paper we use simulation methods to estimate ergodic and outage capacities, and outage probabilities for the more general Rician fading channel model.

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.

BER of UCA in Rician fading channel

2008 IEEE Antennas and Propagation Society International Symposium, 2008
The modeling of wireless channels vary greatly in different propagation environments. For example, the line-of-sight (LoS) radio links and non-line-of-sight (NLoS) are two basic channel models in wireless communications, but they are totally different from each other. For a LoS channel, if the signals propagate in an additive white Gaussian noise (AWGN)

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 ...

Effect of Channel Estimation Errors on MRC Diversity in Rician Fading Channels

IEEE Transactions on Vehicular Technology, 2005
We study the effect of imperfect channel estimation (ICE) on the performance of M-ary phase shift keying (M-PSK) with maximum ratio combining (MRC) in generalized Rician fading channels. First, we derive the error probability formulas for M-PSK with MRC and ICE in arbitrary Rician fading channels.
