Abstract
A digital TDMA automobile telephone having a receiving circuit includes a receiving period control unit having a receiving period processing part, a control switch, and a field intensity detecting circuit or a bit error detecting circuit. The receiving period control unit is connected to the receiving circuit to determine an optimum receiving period according to the field intensity of a received signal or bit errors therein, which are detected during reception of a radio wave, thereby stabilizing the reception. In addition, the control switch is on/off controlled on the basis of the determined receiving period to thereby control the power supply for the receiving circuit.
