Abstract:
1. A receiver for receiving a signal transmitted by a Differential Space-Time Block Coding (DSTBC) method, characterized by comprising: a receiving unit which receives a signal transmitted from the transmitting side, where a frame having a synchronous word arranged in a predetermined place is used, and the entirety of said frame including said synchronous word is encoded by the DSTBC method; an A/D converting unit which A/D converts a signal received by said receiving unit; a downsampling unit which downsamples the received signal after being A/D converted by said A/D converting unit; a first DSTBC decoding unit which decodes by the DSTBC method the signal downsampled by said downsampling unit; a second DSTBC decoding unit which decodes by the DSTBC method the received signal before being downsampled by said downsampling unit and after being A/D converted by said A/D converting unit; a synchronous word information storing unit which stores information corresponding to said synchronous word before being encoded by the DSTBC method; a correlation value acquiring unit which acquires a correlation value between the signal resulting from the decoding by said second DSTBC decoding unit and said synchronous word stored in said synchronous word information storing unit; and a sampling timing control unit which controls the sampling timing for said A/D converting unit on the basis of the correlation value acquired by said correlation value acquiring unit.
