Provided are a multi-pilot generation method and a detection method in a multi-antenna communication system. In the method, a transmission side superimposes a first preamble sequence and a third preamble sequence to generate a second preamble sequence, which is subjected to serial/parallel conversion before the first preamble sequence and the second preamble sequence are successively transmitted from a plurality of antennas by time division. A reception side receives the first preamble sequence and the second preamble sequence by a plurality of antennas, separates the third preamble sequence from the second preamble sequence by a spatial division process, and performs a pilot correlation process by using the first preamble sequence and the separated third preamble sequence.
