1. A transmitter system, comprising:
- a digital phase rotator, arranged to receive a first constellation data and apply a digital phase rotation to the received first constellation data to generate a second constellation data;
a phase rotation controller, arranged to configure the digital phase rotation; and
a digital radio-frequency (RF) transmitter, arranged to receive a digital input data derived from the second constellation data, and process the digital input data for transmission of an analog RF output;
wherein the analog RF output is generated through at least one digital power amplifier; and
a configuration of the digital phase rotation is dependent upon at least one characteristic of the digital RF transmitter.

Abstract
A transmitter system includes a digital phase rotator, a phase rotation controller, and a digital radio-frequency (RF) transmitter. The digital phase rotator receives a first constellation data, and applies a digital phase rotation to the received first constellation data to generate a second constellation data. The phase rotation controller configures the digital phase rotation. The digital RF transmitter receives a digital input data derived from the second constellation data, and converts the digital input data into an analog RF output.
