Abstract

In this paper, we present an efficient wave propagation model that supports both urban canyon and urban canyon situated indoor propagation based on a hybrid of the ray tracing and finite volume/finite difference time domain methods. The model is provided in a high-performance compact terrain database (CTDB) format with multi-elevation structure for use in high-resolution dynamic simulators. The effect of multipath propagation on the multiple access methods and the comparison of the WCDMA receiver against that of the UFO receiver in the urban setting is discussed. Simulation includes the bit-error-rate for a given satellite power, and the power needed at the satellite for a given bit-error-rate subject to the maximum beam power, which determines the relative fraction of the total time the signal is acquired for the two models. the simulation results of access control or power control based on urban multipath environment are also presented.
