Abstract
One of the embodiments of the present disclosure relates to a method for PARP reduction. The method comprises iteratively adjusting, based on a computed peak power value for a combined transmission signal including respective components of a plurality of frequency resource units, a phase rotation vector which is applied to said respective components of said plurality of frequency resource units to perform phase rotation on said respective components of said plurality of frequency resource units, until a newly-computed peak power value dependent upon the adjusted phase rotation vector is lower than or equal to a pre-defined peak power threshold or an iteration number reaches a pre-defined maximum value; performing phase rotation on said respective components of said plurality of frequency resource units by applying the adjusted phase rotation vector; and transmitting the combined transmission signal of said respective components of said plurality of frequency resource units phase-rotated by said adjusted phase rotation vector. The present disclosure also relates to corresponding transmitter.
