ABSTRACT:
A multiple access transmitting method in communication resources using a multicarrier signal in which subcarriers of a predetermined number are allocated with a predetermined frequency separation, includes a coding processing step of processing a plurality of individual signals generated from a plurality of signal sources, respectively, a multiplexing step of multiplexing output signals obtained in the coding processing step, and a converting step of converting an output signal obtained in the multiplexing step into a multicarrier signal. A multiple access receiving method in communication resources using a multicarrier signal in which subcarriers of a predetermined number are allocated with a predetermined frequency separation, includes a converting step of converting a received multicarrier signal into an information including every subcarrier, a demultiplexing step of demultiplexing output signals obtained in the converting step and of generating plurality of codes, and a coding processing step of processing a plurality of individual signals generated in the demultiplexing step.
