    摘要： A wireless communication unit comprises a transmitter comprising a power amplifier, an inner feedback power control loop having a power control logic module comprising loop priming logic module operably coupled to the power amplifier, and a switchable outer digital loop comprising switchable logic module. The loop priming logic module is arranged to set a power reference value for controlling the power amplifier prior to a ramping operation of the power amplifier and the switchable logic module switching the switchable outer digital loop on or off, thereby restricting adverse transient behaviour of the power amplifier.

    摘要： An all digital model of nonlinear transmitter signal distortion in signals received at a receiver of a transmitter-receiver may be used to estimate distortion. The estimated distortion may then be cancelled from the received signals to improve signal quality of the received signal. The digital nonlinear model may be part of an estimator circuit that estimates nonlinear distortion terms by applying a formula or transformation to a digitized version of the signals transmitter at a transmitter of the transmitter-receiver. A mixer may be used to shift a frequency of the estimated nonlinear terms away from a transmitter frequency so that the nonlinear terms can later be subtracted from the incoming signal received at the receiver at a receiver frequency. Circuits and methods are provided.

    摘要： A wireless communication unit includes a transmitter for processing a baseband transmit signal to produce a first radio frequency signal. A receiver is arranged to convert a second radio frequency signal to a baseband receive signal, where the receiver has a summation module arranged to add a cancellation signal to the baseband receive signal. A selectivity element is arranged to couple the transmitter and the receiver to an antenna, where a reduced portion of the first radio frequency signal is introduced into the second radio frequency signal thereby creating a second order inter-modulation distortion component in the baseband receive signal. An adaptive estimator module has a filter for filtering the baseband receive signal to remove dc offsets associated with the second order inter-modulation distortion component and generate the cancellation signal based on the baseband transmit signal and the filtered baseband receive signal for inputting to the summation module.

    摘要： A wireless communication unit comprises a transmitter having a forward path comprising a power amplifier, PA, and a feedback path arranged to feed back a portion of a signal output from the PA to a point in the forward path prior to the PA. The forward path and feedback path form a constant gain tracking (CGT) loop. The feedback path comprises an adaptive predistortion logic module located outside of the CGT loop and arranged to form an APD loop with the forward path and feedback path. The CGT loop comprises a controller logic module arranged to determine a gain offset of a signal routed through the forward path and feedback path and in response thereto set a drive level of the PA.
