Evaluation of bit error rate (BER) of digital communication systems is usually done via simulation using Monte Carlo (MC) method. For low BER, MC method requires huge sample sizes to achieve certain efficiency. To overcome this limitation, many variance reduction techniques such as importance sampling (IS) have been proposed. In this paper, a novel simulation method Monte Carlo simulation with error...
Investigates on the confidence probability of Monte Carlo (MC) simulation results for bit error rate (BER) evaluation under the condition of uncorrelated multipath-path Rayleigh fading channels. Based on the principles and conclusions of Monte Carlo methods and the analysis of statistics characteristics for Rayleigh Fading Channels, the correlation function of the instantaneous BER by MC method is...

A beamforming approach is developed for mobile wireless systems operated in vehicular scenarios such that the channel undergoes fast Rayleigh fading. In this approach, the downlink beamforming weights of the base antennas are generated based on the orthogonal basis of the uplink signal subspace. The downlink transmission to a particular mobile is through its effective signal subspace via multiple...
