In this paper, we investigate a new turbo-detector scheme. The data detection part of the iterative receiver is based on variants of full-states SOVE and SOVA Interference InterSymbols (ISI) decoders. Those variants employ reduced-state techniques combined with generalized per-survivor processing. They offer a very good trade-off between performance and complexity even with long delay channels. Monte-Carlo simulation results in various severe propagation environments show that the proposed sub-optimal turbo-detector is usually 1,8 to 3 dB away from the optimal BCJR-based one with a significant computational complexity reduction. Hence it appears as a possible candidate for future mobile radio communications with high bit rate transmission.
