摘要： A method for determining reserved tone set to be used for reducing a Peak to Average Power Ratio (PAPR) is provided in a transmission apparatus of an Orthogonal Frequency Division Multiplexing (OFDM) communication system. The shift value is determined based on a subcarrier spacing interval(x) and a number of spaced symbols(y) of a scattered pilot pattern and OFDM symbol indices(1). The reserved tone set( S l ) for OFDM symbols is determined by shifting each of subcarriers( i k ) of a predetermined reserved tone set( S 0 ) by the determined shift value.
