Enhanced Algorithm for Simulation of Power Spatial-Temporal Distribution in Cellular Environments

Luo Fei Du Ming-hui (School of Electronic and Information Engineering,South China Univ.of Tech.,Guangzhou 510640,Guangdong,China)  
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 introduced to propose an enhanced simulation algorithm based on the Geometrically Based Single Bounce Elliptical Mo-del (GBSBEM).The enhanced algorithm can characterize the power spatial-temporal distribution in cellular environments more 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,while in the prediction of power azimuth spectra,the former is of a smaller mean-square relative error than the latter.
