Bounds on the error performance of coding for nonindependent Rician-fading channels
IEEE Transactions on Communications, 1992New upper bounds on the error performance of coded systems for Rician channels are presented. The fading channels need not be fully interleaved to obtain meaningful performance results. These bounds hold for coherent, differentially coherent and noncoherent demodulation of binary signals.

Performance Analysis of LDPC on Rician Fading Channels
Frontiers of Electrical and Electronic Engineering in China, 2006This paper analyzes and simulates the performance of irregular low-density parity check (LDPC) codes on Rician fading channels. The authors also modified the brief propagation decoding algorithm, proved the symmetry and showed the stability conditions of the channels, and calculated the Shannon limits on Rician channels in this paper. By using Visual C+

Evaluation of M-ary Rician fading channel
Proceedings of Southeastcon '93, 2002The system performance of M-ary orthogonal signaling over a Rician fading channel is evaluated. The probability of error expression for a suboptimal receiver is developed for the Rician fading channel using M orthogonal signals. The near-optimality of this receiver is demonstrated by comparing simulation results for both the optimum and the suboptimum ...

Impact of correlated diversity branches in Rician fading channels
IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005The effect of correlated branches on the performance of coherent maximum ratio combining (MRC) and non-coherent equal gain combining (EGC) diversity receivers over Rician fading channels is studied. The asymptotic error and outage probabilities for the MRC and EGC receivers with arbitrarily correlated branches for high average signal-to-noise ratios ...

Effect of Channel Estimation Errors on MRC Diversity in Rician Fading Channels
IEEE Transactions on Vehicular Technology, 2005We 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.

Linear diversity analysis for QAM in Rician fading channels
2014 23rd Wireless and Optical Communication Conference (WOCC), 2014An exact and general closed-form expression of the Bit Error Rates (BER) for rectangular type of Quadrature Amplitude Modulation (QAM) over slow, flat, Rician fading channels are derived analytically when the Maximal-Ratio Combining (MRC) technique is applied to mitigate degradation from multipath fading and fluctuation.

Performance of Viterbi Decoding on Interleaved Rician Fading Channels
2018 IEEE International Symposium on Information Theory (ISIT), 2018In this paper, we investigate the performance of the Viterbi decoding algorithm with/without Automatic Repeat reQuest (ARQ) over a Rician flat fading channel with unlimited interleaving. We show that the decay rate of the average bit error probability with respect to the bit energy to noise ratio is of order between $d_{f}$ and $d_{f}+1$ at high ...

Ultra-wideband signals in a Rician fading channel
IEEE 60th Vehicular Technology Conference, 2004. VTC2004-Fall. 2004, 2005This paper presents an analysis of the link performance of ultra-wideband (UWB) signals using a new figure of merit which is based on ability of UWB signals to mitigate the effect of channel fading. The new figure of merit is defined as the coefficient of variation (CV) of the received wideband signal power, which is a measure of the variation in the ...
