Diversity system and diversity method

摘要

A synchronous signal position detection unit detects symbol synchronous signals according to OFDM from the signals received by the respective antennas. A delay measurement unit measures a relative delay between the symbol synchronous signals for each antenna series and makes a notice to a memory unit via a delay amount notification unit. A diversity operation implementation unit temporally aligns the carrier data positions of the OFDM symbols for each antenna series so as to implement a space diversity operation.
