Abstract

The low peak-to-average power ratio (PAPR) in single- carrier systems has motivated the Long Term Evolution (LTE) Third Generation Partnership Project (3GPP) to adopt single carrier frequency division multiple access (SC-FDMA) as the uplink multiple access scheme. In a single-carrier (SC) system, traditional time domain pulse shaping is used to bandlimit the transmit signal. In this paper we show that by applying a frequency domain spectral shaping filter to SC-FDMA, the PAPR of a localized FDMA (LFDMA) signal can be further reduced at the expense of degraded bandwidth efficiency. Simulation results show that a PAPR reduction of 1.3 dB can be achieved for LFDMA when a raised cosine frequency domain spectral shaping filter with a roll-off factor of 0.22 is applied. Compared to the unfiltered system, the resulting bandwidth efficiency is 78.1%. This PAPR reduction can be used to enhance the power efficiency of the handset, or alternatively to improve uplink throughput and/or operating range.
