TRANSMITTER SYSTEM WITH DIGITAL PHASE ROTATOR USED FOR APPLYING DIGITAL PHASE ROTATION TO CONSTELLATION DATA AND RELATED SIGNAL TRANSMISSION METHOD THEREOF

摘要

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.
