摘要：

In this paper, we develop an effective method, Multicarrier Parallel Decision Feedback Decoding (MC-PDFD), to combat the residual ISI (intersymbol interference) effect in OFDM systems employing multi-dimensional trellis-coded modulation, (TCM) scheme. The proposed method operates on reduced-state trellises with modified branch metric in order to accommodate OFDM and other multicarrier communications. MC-PDFD: combines the tasks of trellis decoding and equalization, altogether and removes the residual ISI simultaneously with decoding process. Simulation results show that MC-PDFD works well in different channel conditions with perfect channel information and degrades slightly with non-perfect channel. information.
