Wireless communication unit and power control system thereof

摘要

A wireless communication unit (100) comprises a transmitter having an analogue feedback power control loop having a power control function (132) arranged to set an output power level of the transmitter. The power control function (132) comprises a predictor sub-system (200) arranged to reduce sensitivity to loop latency of the analogue feedback power control loop. The use of a predictor sub-system provides reduced sensitivity to loop latency, gain variations and delay.
