METHOD OF TRANSMITTING MULTI CODEWORD IN MULTIPLE ANTENNA SYSTEM

摘要

PURPOSE: A method of transmitting a multi codeword in a multiple antenna system is provided to transmit a multi codeword having a low PAPR(Peak to Average Power Ratio) in an SC-FDMA system based on a multi antenna. CONSTITUTION: Parallel codewords are generated by encoding plural parallel information bit strings, and modified symbol strings are generated by modulating the parallel codewards. Frequency division symbol strings are generated by performing a DFT(discrete Fourier Transform), and are precoded. The precoded frequency domain symbols are mapped to resource elements, and an SC-FDMA(Single Carrier Frequency Division Multiple Access) symbol is generated by performing an IFFT(Inverse Fast Fourier Transform) for the frequency domain.
