ABSTRACT:
A radio communication system comprises a plurality of personal terminals and a base station, the personal terminal being equipped with a non-directional antenna or a directional antenna directed to the base station, which transmits and receives a signal at an identical frequency, the base station, which establishes a communication path between the personal terminals by relaying of the signals, comprising a non-directional transmitting antenna and a receiving antenna located in such a positional relationship as to minimize the amounts of the signals coupled at the respective antennas, and feeds the received signal received by the receiving antenna to the transmitting antenna while cancelling a leakage signal from the transmitting antenna which is contained in the received signal, by using a reference signal set on a given frequency channel which may be modulated with a broadcast signal.
