PROBLEM TO BE SOLVED: To realize a communication system that does not generate synchronizing timing error of a receiver in a case a signal from a specified antenna is not received, and can discriminate from which antenna a signal is received in case any information series is transmitted in a radio communication system in which a transmitter with a plurality of transmission antenna communicate with a receiver. SOLUTION: The device comprises a coding means which inputs information series, and creates a coding series respectively corresponding to the plurality of transmission antenna, a mapping means which performs different mapping from signal point mapping performed on other series for at least a series out of coding series respectively corresponding to the plurality of antenna, and creates a mapping series respectively corresponding to the plurality of transmission antenna, and a modulation means which is installed corresponding to the plurality of antenna, and performs modulation processing for each mapping series respectively.
