Abstract:

In order to make a better simulation of the power spatial-temporal distribution in cellular environments ,two concepts with definite physical meanings , namely "effective scatterer" and "reflecting probability" , are introducedto propose an enhanced simulation algorithm based on the Geometrically Based Single Bounce Elliptical Model(GBSBEM). The enhanced algorithm can characterize the power spatial-temporal distribution in cellular environmentsmore accurately and flexibly. the comparison between the simulated and the measured results shows that ,in the prediction of power delay spectra , the enhanced algorithm and the GBSBEM are of the same precision , whilein the prediction of power azimuth spectra , the former is of a smaller mean-square relative error than the latter.

Key words: radio broadcasting, spatial-temporal distribution, geometrically based single bounce elliptical model, power delay spectrum, power azimuth spectrum
