ABSTRACT:
A method and apparatus that reduces the amount of constellation rotation due to power amplifier (PA) insertion phase variation during activation (i.e., turn on) of a transmitter. This is accomplished by applying an instantaneous phase rotation during the transmitter turn on at digital baseband to counteract and minimize unwanted phase variations.
