WIRELESS COMMUNICATION SYSTEM FOR HIGH-SPEED VEHICLE TRAVELLING OVER FIXED PATH

WIPO Patent Application WO/2011/045665

A3

The present invention discloses a method for transmitting a pilot sequence from a transmitting end to a receiving end in a multi-antenna wireless communication system. In particular, the method comprises the steps of: setting an identical pilot pattern in a plurality of transmitting antennas; allocating respectively different pilot sequences to the set pilot patterns; and transmitting the allocated pilot sequences to the receiving end, wherein at least one of the transmitting antennas forms a valid communication link with one of the receiving antennas. Here, when there is a plurality of valid communication links, the plurality of communication links are mutually independent.
