RADIO COMMUNICATION SYSTEM EMPLOYING DIRECTIVITY-CONTROLLABLE ANTENNA, AND RECEIVING APPARATUS THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a radio communication system including a directivity-controllable antenna, and a receiving apparatus therefor which perform communication on an appropriate communication path and even when one of communication paths is shut out by an obstacle, stably perform transmission/reception without interruption by switching the communication path to another communication path. SOLUTION: The receiving apparatus includes: an appropriate path selecting means for selecting an appropriate signal wave communication path; and an antenna control section which turns directivity of a directional antenna toward the appropriate communication path selected by the appropriate path selecting means and causes the directional antenna to receive a signal wave passed on the appropriate communication path. The appropriate path selecting means always measures received power and delay dispersion of a plurality of signal waves including the signal wave being received at present and selects the appropriate signal wave communication path on the basis of the measured received power and delay dispersion and the antenna control section operates so as to cause the directional antenna to continuously receive signal waves having passed on the appropriate communication path.
