Applied Mechanics and Materials
DFT-S OFDM, short for DFT Spread OFDM, is employed in LTE uplink to reduce the Peak-To-Average Power Ratio (PAPR) introduced by multicarrier transmission. In this paper, we compare the maximum achievable data rate, i.e. the Shannon capacity, of DFT-S-OFDM and OFDM under Rayleigh and with clipping. Our results indicate that, in terms of Shannon Capcity, OFDM outperforms DFT-S-OFDM with ZF or MMSE.
