Abstract:
A wireless communication unit comprising a transmitter having a power amplifier, a controller logic module arranged to control a power control value of the power amplifier and a closed loop control system operably coupled to the power amplifier and arranged to monitor a level of peak PA compression, wherein in response to the identified level of peak PA compression the controller logic module is arranged to automatically adjust a power amplifier power control value of the PA to obtain a predetermined level of peak PA compression.
