a continuous channel estimation and tracing method is needed to implement the Viterbi algorithm of MLSE because of fading and Doppler effect.In this paper
we propose a novel MLSE receiver based on interpolating channel processing (ICP).To reduce the computational complexity of VA
we use an effective method named-adaptive threshold algorithm (ATA).A comparison in performance and computational cost is given with two other reference algorithms:Per-survivor Processing and Minimum Survivor Processing.
