摘要： 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.

摘要： A slot-based low Intermediate Frequency (‘IF’) radio receiver comprises an IF local oscillator for producing I and Q IF local oscillator signal components in phase quadrature, I and Q mixer channels for mixing the input signal with the I and Q IF local oscillator signal components to produce I and Q IF signal components. The IF local oscillator includes frequency alternation means for causing the IF local oscillator frequency to alternate a plurality of times during each frame between first and second values, one of which is greater and the other smaller than the desired carrier frequency of the input signal so as to reduce the effect of adjacent and alternate interferers. The phase of the baseband local oscillator is alternated in synchronism with the alternation of the IF local oscillator frequency.

摘要： Methods in radio communications devices having a transmitter with an integral control loop, and in other integral control systems, including generating a first error signal (210) based upon an amplifier output signal and a corrected reference signal, generating a second error (220) signal based on a closed loop integral control signal applied to a control input of the amplifier and based on an integral control reference signal, and generating the corrected reference signal (230) by correcting a reference signal based upon the first and second error signals.
