摘要：
A communication method, and a processing in accordance with the priority can be performed with a simple configuration even in the case of the communication of the multi-carrier method. The sub-carriers on which high priority data is superimposed and the sub-carriers on which low priority data is superimposed are positioned alternately to be transmitted. At the receiving side, the reception symbol stream in which symbols are lined on the frequency axis is obtained by performing a predetermined reception processing. The delayed symbol stream in which the reception symbol stream is delayed for a predetermined time is added to the reception symbol stream to extract the signal components relating to the high priority data, so that the high priority data is decoded. Thus, the high priority data can be decoded promptly with a simple configuration, and a processing in accordance with the priority can be performed with a simple configuration even if the high priority data and the low priority data are transmitted at the same time by the multi-carrier method.
