RADIOPHONE AND METHOD FOR TIME-INTERVAL CALIBRATION OF PAGE-MODE CLOCK SIGNAL IN CODE- DIVISION MULTIPLE-ACCESS RADIOPHONE SYSTEM Russian patent published in 2002 - IPC

FIELD: radio communications. SUBSTANCE: radiophone and radiophone system enter in quiescent state at low input power and quiescent time is measured using synchronized quiescent-time pulse generator having low resolving power. Radiophone brings division of its time intervals in synchronism with that of system using generator of high resolving power. Then radiophone quits quiescent conditions synchronized with system division of time intervals at low input power. EFFECT: reduced power requirement of portable radiophones. 10 cl, 5 dwg
