APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING PILOT SIGNALS IN A COMMUNICATION SYSTEM USING AN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SCHEME

摘要

Disclosed is a method for providing a pilot symbol for base station identification in a Multiple-Input Multiple-Output (MIMO) communication syst em having one or more transmission antennas, wherein the pilot symbol is comprised of a first sequence having a good cell identification characterist ic and a second sequence for reducing a peak-to-average power ratio (PAPR) for all of pilot symbols.
