Abstract :
In this paper we present and compare several low-complexity approaches for soft-output equalization using reduced-state sequence estimation (RSSE) for EDGE. The proposed approaches require only a forward equalization pass and have the same complexity as hard-output RSSE equalization. However, they offer performance gains close to more complicated approaches that require both forward and backward passes.
