Abstract

An OFDM system includes a frequency-time transformer configured to receive and transform input data to be transmitted to a time-domain sequence; a serial/parallel transformer configured to divide the time-domain sequence into plural sequences; a phase rotating module configured to perform phase rotation in respects to each of the divided time-domain sequences; and a minimum PAPR signal selector configured to select a sequence having a minimum peak-to-average power ratio (PAPR) among the sequences outputted from the phase rotating module.
