Abstract:
A base station device and a method for multi-carrier crest factor reduction are provided. The method includes generating, using a plurality of radio frequency sources, a plurality of radio frequency carrier signals. The method also includes initiating modulation, using a plurality of carrier modulators, of a first subset of the plurality of radio frequency carrier signals with information signals at a first time to generate a plurality of modulated signals and initiating modulation, using the plurality of carrier modulators, of a second subset of the plurality of radio frequency carrier signals with the information signals at a second time to generate the plurality of modulated signals. The second time is a predetermined time offset after the first time. The method also includes transmitting, using one or more antennae, a multi-carrier signal including the plurality of modulated signals.
