ORTHOGONAL FREQUENCY-DIVISION MULTIPLEXING (OFDM) TRANSMITTING AND RECEIVING DEVICE FOR TRANSMISMITTING AND RECEIVING AN OFDM SYMBOL HAVING SYMBOLS INTERLEAVED VARIABLY, AND METHODS THEREOF

摘要

An orthogonal frequency-division multiplexing (OFDM) device is disclosed. The OFDM device includes a transmission processing unit to generate subcarriers having different priority levels, an interleaving unit to sequentially select one of a predetermined plurality of interleaving rules, and to interleave the subcarriers, and a transmitting unit to output an OFDM symbol consisting of the interleaved subcarriers through a wireless channel. This prevents continual fading from occurring.
