Transmission of a plurality of sub-carriers in an OFDM signal

摘要

A method of transmitting a plurality of sub-carriers in a plurality of OFDM signals. During a given transmission time, an OFDM signal transmits a plurality of sub-carriers which act as synchronizing pilot symbols. The transmission of the pilot sub-carriers in a given OFDM signal at a given time are coordinated as not to interfere with sub-carriers transmitted by other OFDM signals. The OFDM signals are transmitted in the same frequency band from a plurality of antennas.
