Abstract

PURPOSE:To always select and receive an electric wave of a good receiving state without having the complicated switching of reception, by always measuring the receiving level by a measuring signal receiver and then switching the carrier frequency received by a signal receiver for communication according to the contents of the above-mentioned measurement of the signal level. CONSTITUTION:The transmission given from the 1st base station that transmits the 1st frequency as a carrier wave and the transmission from the 2nd base station that transmits the 2nd frequency as a carrier wave are switched and received by a measuring signal receiver 4. Then the signal showing the receiving level of each transmission is delivered, and the process of the output signal is stored 5. The receiving level to the carrier frequency which is under reception is detected to be lower than the receiving level to other carrier frequencies according to the contents of the storage device 5. In this case, the switching 7 is carried out to receive another frequency.
