摘要
A technique for controlling the transmission power level of a transmitter, particularly in a wireless personal communication system, is disclosed. This technique assists in the prevention of interference between transceivers from degrading the quality of transmissions. Transmission power level is controlled through a hybrid circuit containing both digital and analog electronics. The transmission power level is set by controlling both the amount by which a data stream is compressed and the gain of an analog transmit power amplifier. This approach allows adequate control over the transmission power level; it avoids the need for utilizing excessively wide data paths for the digital transmit signals (which may compromise portable terminal battery consumption), or utilizing expensive, hard-to-calibrate analog electronics.
