摘要：
A method for encoding an OFDM signal includes pairing two adjacent subcarriers of an OFDM signal as a group, changing a modulated symbol set of the OFDM signal to a modified symbol set for coding the OFDM signal, and providing a modified baseband OFDM signal with an increased frequency separation between the subcarriers and reducing the total number of subcarriers being used for transmission over each OFDM symbol interval.
