METHOD AND APPARATUS FOR ALLOCATING SUBCARRIERS IN OFDMA

摘要

A method and an apparatus of allocating subcarrier in a multiple subcarrier system is provided to have a low PAPR(peak to average power ratio) and high ICI(Inter Channel interference) between adjacent channels in an OFDMA(Orthogonal Frequency Division Multiple Access) wireless communication system. Serial data symbols are converted into parallel data symbols. The parallel data symbols are grouped into at least two data symbol groups. At least two data symbol groups are allocated to at least one subcarrier group, in which at least one subcarrier group is formed by grouping plural subcarriers. Each of the data symbol groups is grouped by plural neighbor data symbols.
