Improved power control of RF signals

摘要

A power control loop for a BTS (Base Transceiver System) is described which allows the power control to take into account compensating values which are detected during guard periods between signal bursts in an RF communication system. The power amplification factor is thus modified in dependence on the detected level of the amplified signal in a feedback loop, modified by the compensating value. This is used to remove an offset voltage Voff which exists in the guard period. Use in a TDMA system is described.
