Abstract:
A device for controlling spectral regrowth includes a transmission signal processor configured to generate a baseband transmission signal and a controller. The controller is configured to adjust delay of an envelope tracking path that provides a supply voltage to an envelope tracking power amplifier included in a transmission path that generates a radio frequency (RF) transmission signal from the baseband transmission signal. The controller may obtain allocation information of resource blocks included in the RF transmission signal from the transmission signal processor and may determine the delay of the envelope tracking path based on the allocation information.
