Single carrier frequency division multiple access (SC-FDMA) for filter bank multicarrier communication systems

Abstract

The Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) radio standard has adopted a special form of orthogonal frequency division multiplexing (OFDM) method for the uplink of multiple access networks. This method which is called single carrier frequency division multiple access (SC-FDMA) applies a precoding to each user data set in each OFDM symbol to control its peak-to-average power ratio (PAPR). In this paper, we present a novel formulation of the SC-FDMA and explore possible mimicking the same method when filter bank multicarrier (FBMC) is used for transmission. We find that such direct application of SC-FDMA to FBMC systems is not successful. However, we show that FBMC techniques offer other opportunities that when used correctly lead to a significant reduction in PAPR.
