Predicting propagation path and strength of wireless signals in Microcell Scenarios

The ray-tracing technique with image approach is applied in the microcellular system which is widely used in mobile communication system. The algorithms of effective catopter based on a modified IMG method are given in detail. Diffracted paths are broken up into several reflected paths to deal with. The stochastic simulation method based on the spatial dispersion to calculate the probability density function of amplitude to the single-frequency multiple-wave interference problem is proposed.
