In this paper, we studied on the detection algorithm for Trellis-coded modulation(TCM) signaling scheme using delayed decision feedback sequence estimation(DDFSE) in the presence of intersymbol interference(ISI).
As the modulation signal scheme use to DDFSE, trellis coded QPSK on a channel with intersymbol interference is considered.
It shows that the presented scheme has a significant advantage since the complexity of this algorithm to be reduced less than MLSE viterbi algorithm. And also, estimates on the performance of DDFSE are given, and simulation results are provided.
