RAY TRACING METHOD AND APPARATUS INDEPENDENT FROM POINTS OF TRANSMITTER AND RECEVIER

摘要

PURPOSE: A ray tracing method which is independent from a transmitting and receiving spot and a device thereof are provided to measure propagation loss about a corresponding pathway after selecting a transceiver path is selected against sides which are contiguous to a transmitting and receiving location. CONSTITUTION: A preprocessing part(610) selects sides in which an electric wave arrives in radio environment. The preprocessing part produces a radio path tree. A main processing part(620) selects a transmitting and receiving path of the sides which are contiguous to a transmitting and receiving location. The main processing part measures propagation loss about the selected transmitting and receiving path.
