Abstract
In this paper, we propose iterative methods to reconstruct the cyclic prefix for coded single-carrier frequency-domain equalization (SC-FDE) systems that employ insufficient length of cyclic prefix at the transmitter. Since the insertion of the cyclic prefix for SC-FDE systems decreases the bandwidth utilization efficiency as the channel's delay span increases, it is desirable to improve the bandwidth utilization efficiency by limiting the length of the cyclic prefix. Two novel schemes for reconstructing the cyclic prefix of coded SC-FDE systems are discussed: one employing the soft output of the decoder and the other employing precoding. The performance of these schemes is shown by computer simulations.
