53. A method for providing a pilot symbol for base station identification in a Multiple-Input Multiple-Output (MIMO) communication system having one or more transmit antennas, the method comprising:
generating, by a pilot signal generator, the pilot symbol,
wherein the pilot symbol is comprised of a first sequence having a good cell identification characteristic and a second sequence for reducing a peak-to-average power ratio (PAPR) for all of pilot symbols,
wherein when the number of the transmit antennas is two and an FFT operation point has a value of 128, the first sequence R(r) is determined by
