RADIO RECEIVER INPUT POWER CONTROL DEVICE AND METHOD FOR CONTROLLING RADIO RECEIVER IN RADIO COMMUNICATION SYSTEM

摘要

FIELD: radio communications. SUBSTANCE: portable radiotelephone 101 incorporated in radio communication system 100 has input-power controller circuit 200. Radiotelephone system 100 is designed so that radiotelephone 101 functions only to receive intermittent pager information from remote transceiver 103 in monitoring mode of operation. Input power controller circuit 200 uses economically efficient low-power and low-frequency generator 237 together with hardware and software to turn off part of radiotelephone 101 when the latter receives information from remote transceiver 103. Running turn-off interval is adjusted depending on accuracy of synchronization during preceding turn-off interval. EFFECT: improved accuracy of input power control. 5 cl, 4 dwge
