There are different possibilities how to generate an SC FDMA signal DFT spread OFDM DFT s OFDM has been selected for EUTRA The principle is illustrated in figure 1 1 For DFT s OFDM a size M DFT is first applied to a block of M modulation symbols QPSK 16QAM and 64 QAM are used as uplink EUTRA modulation schemes the latter being optional for the UE The DFT transforms the modulation symbols into the frequency domain The result is mapped onto the available sub carriers In EUTRA uplink only localized transmission on consecutive sub carriers is allowed An N point IFFT where N gt M is then performed as in OFDM followed by addition of the cyclic prefix and parallel to serial conversion Incoming Bt eam Channd By Fig 1 1 Block Diagram of DFT s OFDM Localized Transmission User Manual 1308 9135 42 13 9 R amp S FS K101 103 105PC Introduction 1 2 2 1 2 3 Long Term Evolution Uplink Transmission Scheme The DFT processing is therefore the fundamental difference between SC FDMA and OFDMA signal generation This is indicated by the term DFT spread OFDM In an SCFDMA signal each sub carrier used for transmission contains information of all trans mitted modulation symbols since the input data stream has been spread by the DFT transform over the available sub carriers In contrast to this each sub carrier of an OFDMA signal only carries information related to specific modulation symbols SC FDMA Parameterizatio
