This paper proposes a modified iterative scheme(MI) for the data transmitted by more efficient way over inter-symbol interference(ISI) channels,then compares and analyzes the performance for three equalization algorithms in MI: improved max-log-map(I-MLM) algorithm,maximum a posteriori(map) algorithm and linear minimum meansquared error(LMMSE) *** we analyze and compare these three algorithms in traditional turbo equalization(TE) ***,according to the good understanding of the aforementioned algorithms and the novel iterative(NI) scheme which combines parallel with serial concatenation turbo-like scheme,we propose the MI scheme and compare the performance of three algorithms in MI, named as MI-I-MLM,MI-map and MI-LMMSE *** analytical and simulation results demonstrate that the performance of MI-I-MLM is very close to MI-map and much better than MI-LMMSE while its computational complexity is much lower.
