Abstract:

A DFT spread generalized multi-carrier (GMC) based frequency division multiple access (FDMA) scheme, i.e. DFT-S-GMC is proposed for uplink transmission of wideband mobile communication systems. The scheme achieves spreading gains in the frequency-do-main by discrete fourier transform(DFT),and the frequency division multiplexing(FDM)and FDMA by inverse filter-bank transform(IFBT). By theoretical analysis and simulation results,it is shown that the proposed scheme has good peak-to-average power ratio (PAPR) perfor-mance and is more robust to the multi-access interference (MAI) than the existed main stream uplink schemes,e.g. OFDMA and DFT-S-OFDMA scheme.

Key words: FDMA, filter-bank, multi-carrier, MAI, PAPR
