摘要： Disclosed is a pilot multiplexing method in an Orthogonal Frequency Division Multiplexing (OFDM) system. Transmit data is transmitted by an OFDM signal through an OFDM scheme, pilot data is directly spread, and a spread-spectrum signal, which has been obtained by spreading, is transmitted in the same frequency band as that of the OFDM signal at the same time in superposition therewith or time-division multiplexed therewith. The spread-spectrum signal is a CDMA signal that has been obtained by spreading the pilot data by a prescribed spreading code.
