Abstract

Single carrier interleaved frequency division multiple access (SC-IFDMA) has been recently receiving much attention for uplink multiuser access in the next generation mobile systems because of its lower peak-to-average transmit power ratio. In this paper, we investigate the effect of carrier frequency offsets (CFO) on SC-IFDMA and propose a new low-complexity time domain CFO compensation (TD-CC) scheme. The TD-CC scheme can be combined with successive interference cancellation technique to further improve the system performance. Simulation results will show that the proposed TD-CC and TD-CC-SIC schemes greatly reduce the CFO effect on SC-IFDMA. Furthermore, we propose a new blind CFO estimation scheme for SC-IFDMA systems, which is based on the ESPRIT algorithm. Compared to the conventional blind CFO estimation scheme using ESPRIT, it is shown that in some cases the proposed scheme does not need to increase the length of cyclic prefix, and thus improve the data throughput efficiency.
