DATA TRANSMISSION METHOD IN A MULTI-CARRIER SYSTEM, AND TRANSMITTER

摘要

The present invention provides a transmitter including a plurality of transmitting antennas, a processor for creating data symbols, and an SC- FDMA (single carrier frequency division multiple access) signal generator for taking, as an input, the data symbols, and generating SC-FDMA symbols to be transmitted through the plurality of transmitting antennas. The SC-FDMA signal generator performs an IFFT (Inverse Fast Fourier Transform) independently of each of the plurality of transmitting antennas, and each of the plurality of transmitting antennas is associated with the plurality of carriers, respectively.
