METHOD OF DATA TRANSMISSION USING EFFECTIVE SUBCARRIER MAPPING

摘要

A data transmission method using an efficient subcarrier wave mapping is provided to efficiently perform a localized mapping and a distributed mapping in all frequency bands at the same time. A logical frame is prepared. A physical frame in which a localized mapping and a distributed mapping are mixed is generated in the same OFDM(Orthogonal Frequency Division Multiplexing) symbol. The generated physical frame is transmitted. The localized mapping(5,6,7) maps adjacent subcarrier waves in the logical frame to adjacent subcarrier waves of the same position of the physical frame. The distributed mapping(1,2,3,4) maps a subcarrier wave of the logical frame to a subcarrier wave of an arbitrary position of the physical frame.
