Method of PAPR reduction for OFDM system using additive mapping sequences and apparatus for the same

摘要

Disclosed are a method for reducing a PAPR of an orthogonal frequency division multiplexing system and an apparatus for orthogonal frequency division multiplexing system for the same. A method for reducing PAPR of an orthogonal frequency division multiplexing system according to an embodiment of the present invention includes partitioning an OFDM symbol sequence into two or more subblocks; Generating an additional mapping symbol subblock corresponding to each of the subblocks; Inverse fast Fourier transforming the subblocks and the additional mapping symbol subblock to generate a signal subsequence and an additional mapping signal subsequence; Generating candidate signal sequences using the signal subsequence and the additional mapping signal subsequences; And selecting a candidate signal sequence corresponding to a minimum PAPR among the candidate signal sequences.
