MULTICARRIER COMMUNICATION METHOD, TRANSMITTER AND RECEIVER

摘要

When multiplexing channels which conduct communication at various transmission rates, each communication is made capable of conducting communication processing, such as information reception, with a minimum required processing amount needed by itself. In order to achieve this object, a plurality of communication channels are set in a predetermined band, and communication in each of the set channels is performed by using a multi-carrier signal having transmission symbols distributed among a plurality of subcarriers. Transmission symbols of each channel on a frequency axis are arranged at intervals of Nth power of 2 (where N is an arbitrary positive number) with respect to a reference frequency interval for transmission. From the transmission signal, a signal component of a required channel is received. <IMAGE>
