Rician channel characterization in OFDM systems
2015 23rd Iranian Conference on Electrical Engineering, 2015Rician 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, 2004Several 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.

BER of UCA in Rician fading channel
2008 IEEE Antennas and Propagation Society International Symposium, 2008The 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)

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.

On the Analysis of Envelope Correlation and Spectra for Rician Fading Channel
Wireless Personal Communications, 2008Physical fading radio channels encountered in wireless mobile communication are often modeled as a complex Gaussian process whose envelope is statistically described by Rayleigh or Rician probability distribution function (PDF). In most of the literature, the accuracy of the simulation model is estimated by comparing the simulated autocorrelation ...

User Capacity of Rician and Nakagami Fading Broadcast Channels
IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008In this paper, we extend the results on the maximum number of active users maintaining minimum rate Rmin > 0 in broadcast channels, known for Rayleigh fading to the cases of Rician and Nakagami fading models. Under the assumption of independent Rician fading channels for different receivers, as the total number of receivers n goes to infinity, the ...

An Accurate and Compact Rayleigh and Rician Fading Channel Simulator
VTC Spring 2008 - IEEE Vehicular Technology Conference, 2008A stochastic sum-of-sinusoids based simulation model is proposed for Rayleigh and Rician fading channels. The time-averaged statistical properties of the new model have been significantly improved compared to existing models. Verification of the proposed fading simulator is carried out by comparing its measured statistical properties with the ...

Performance of hierarchical diversity over correlated rician channels
2014 IEEE Global Communications Conference, 2014We study the performance of multi-branch hierarchical combining diversity systems. Closed-form expressions are derived for asymptotic error rate and asymptotic outage probability of hierarchical selection-combining maximal-ratio combining (SC-MRC) and selection-combining equal-gain combining over Rician channels with arbitrary correlation.

On the design and selection of convolutional codes for a bursty Rician channel
1994This work addresses code design and code selection rules under power and decoding delay constraints for antipodal (BPSK) modulated and convolutkmally encoded communication system. The system operates over a slowly-fading AWGN channel, described here by the ‘block fading’ model.
