Abstract
STTD encoding is signal processing carried out when a base station performs diversity transmission in open-loop mode to a mobile station. The STTD encoding method according to the present invention applies reverse STTD encoding on a pilot signal that should not be subjected to STTD encoding beforehand. Then, the multiplexer time-multiplexes the pilot signal with transmission data and control data to compose a transmission frame. Then, all data included in the transmission frame is subjected to STTD encoding. Applying reverse encoding before frame composition eliminates the need for distinguishing data to be encoded from data not to be encoded during STTD encoding.
