Abstract

A simple detection scheme which can be easily implemented without maximum likelihood sequence estimation (MLSE) is proposed. It has a two-stage structure and makes ¯nal decisions after eliminating inter-symbol interference (ISI) due to both past and future symbols by using tentative decisions. Computer simulation results demonstrate that the proposed scheme can have a comparable performance to that of a tentative decision (TD)-MLSE when the number of resolvable channel paths is two, although its performance degrades as the number of resolvable channel paths increases.
