The present invention relates to a method for inserting the transmission signal of the multiple transmit antennas, and relates to an orthogonal frequency division multiplexing (OFDM) communication system having a receive antenna, and more particularly, OFDM systems, such as the distributed pilots (SPs) Thus, the scattered pilot a method for estimating the channel characteristics on the basis of, to a multi-antenna OFDM transmitter and an OFDM receiver. In this connection, a special approach of the invention is to maintain the same SP pattern as in the case of a single transmitter, and divides the pilot to a subset of the by the presence of the transmitter (transmit antenna), and the time and frequency of these sub-sets which is interleaved at all. In this manner, the particle size of the pilots in the same sub-set is reduced. This point provides greater accuracy and increased flexibility, the estimated channel characteristics to design the distributed pilot pattern.
