Abstract:
1. A transmission method comprising: generating a plurality of orthogonal frequency division multiplexing (OFDM) frame signals, each OFDM frame signal including multiple frequency subcarriers and multiple time periods, where an OFDM symbol is transmitted using multiple frequency subcarriers during a time period; one of the OFDM frame signals including different OFDM data symbols than another of the OFDM frame signals, at least one of the plurality of OFDM frame signals including OFDM pilot symbols assigned to predetermined frequency subcarriers of the multiple frequency subcarriers at predetermined time periods of the multiple time periods, and the other OFDM frame signal including OFDM data symbols assigned to the predetermined frequency subcarriers at the predetermined time periods; converting the OFDM frame signals to radio signals; and transmitting each of the radio signals from a different antenna.
