PURPOSE:To remarkably contrive the reduction of the power consumption during the operation of a small power radio communication equipment by using a 1st detection signal from a 1st detector so as to operate a bit synchronization comparator of a signal processing section and using the 2nd detection signal of a 2nd detector to operate a discrimination code comparator. CONSTITUTION:In receiving a carrier signal lower than a 1st level L by a receiver 3, neither the signal processing of the received data nor transmission is executed and in receiving a carrier signal higher than the 1st level L but lower than a 2nd level H by the receiver 3, a transmitter 4 is not started. Then the 1st detection signal CS-L of a 1st detector 31A starts only a bit synchroniza tion comparator 62A to decide the propriety of the bit synchronization clock of the demodulated data, and when it is decided to be correct, the processing is finished at that time, and when it is decided to be incorrect, the data is stored as a disturbing wave. Since a signal processing section 6 applies no signal processing to discriminate its own station, the power consumption of the receiver is reduced. |
