Abstract

This paper proposes a novel Single Carrier Frequency Division Multiple Access (SC-FDMA) System without Cyclic Prefix based on the Chained Turbo Equalization (CHATUE) algorithm, which connects turbo equalizers neighboring in time to eliminate the Inter-Block Interference (IBI). Results of Extrinsic Information Transfer (EXIT) chart demonstrate that the performance can be improved by performing iterations between neighboring blocks. In addition, this paper also proposes a complexity reduction technique. The numerical results verify the performance improvement and superiority of the proposed technique over the conventional SC-FDMA transmission, without requiring high computational complexity.
