A TRANSMISSION AND RECEPTION METHOD AND APPARATUS FOR AN ORTHOGONAL FREQUENCE DIVISION MULTIPLEXING COMMUNICATION SYSTEM

摘要

inserting reference data having information representing a phase lue and a position into which the reference symbol is inserted, into each of the segmented blocks; IFFT doverse Fast Fourier Transform)-transforming the respective blocks into lime-based signals where sub-carrier frequencies are separately assigned to the data blocks; and determining phase factors of the IFFT-transformed time-based signals to reduce a peak-to-average power ratio (PAPR) where non-linear distortion occurs due to comeidence of phases of the data blocks IFFT-transformed with the sub-earrer frequencies, and phase-rotating the IFFT-translbrmcd signals according to the determined phase factors before transmission.
