The present disclosure relates to a transmitter for transmitting a transmit signal comprising a first signal portion and a second signal portion. The transmitter comprises a power amplifier configured to amplify the transmit signal. The power amplifier is prone to undesired gain variations during the first and the second signal portion. The transmitter further comprises a transmit feedback receiver coupled to an output of the power amplifier and configured to feed back the transmit signal to generate a fed back first signal portion and a fed back second signal portion. Processing circuitry is configured to determine a first gain relation between the fed back first signal portion and the first signal portion and to determine at least one second gain relation between the fed back second signal portion and the second signal portion. Power adjustment circuitry is configured to adjust a transmit power of the transmit signal according to a variation between the first gain relation and the second gain relation.

Early indication for high efficiency fields

Described herein are technologies related to an implementation of a closed-loop system to measure and compensate non-linearity in a transceiver circuitry of a device.

Pre-distortion calibration

A digital phase locked loop operates with a time-to-digital converter and an a-priori-probability-phase-estimation component or estimator component that estimates the un-quantized phase associated with a quantization output of the time-to-digital converter. The time-to-digital converter generates a quantized value as the quantization output from a local oscillator signal of a local oscillator and a reference signal of a reference clock. The estimation component estimates a phase value from the quantized values as a function of a-priori data related to the time-to-digital converter and boundaries of the quantized value.
