Nonlinear equalization for Rician multipath fading channel
2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2004We 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.

On the Spectral Efficiency of VSG CDMA in Nakagami and Rician Fading
IEEE Transactions on Wireless Communications, 2007This paper presents new analytical expressions for the spectral efficiency of Variable Spreading Gain Code Division Multiple Access (VSG CDMA) networks in a Nakagami and Rician fading environments. These are used to gain insight into the impact of fading and background noise on the optimal transmit powers. Numerical results for a dual class and 5-class

Matched filter bound for multipath Rician-fading channels
IEEE Transactions on Communications, 1998This 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, 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)

Optimization of Predetection Switched Combining in Correlated Rician Fading
IEEE Vehicular Technology Conference, 2006The performance of dual-diversity predetection switch-and-stay combining (SSC) in correlated Rician fading is considered in conjunction with several modulation formats. Analytical expressions are derived for the average symbol error rate (SER) of predetection SSC in correlated Rician fading.

Fade margin calculation for channels impaired by Rician fading
IEEE Transactions on Vehicular Technology, 1985Excess path loss due to multipath severely restricts the performance of power limited mobile networks such as those using satellite-aided links. To reduce multipath related losses, the higher elevation angle of the spacecraft can be exploited by utilizing mobile antennas which reduce the strength of the multipath reflections in favor of the line-of ...

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 ...
