Design and Development of a Novel Technique to Reduce Inter-Symbol Interference Using Decision Feedback Equalization

Now a days the scientists main motive is to reduce Inter-symbol Interference (ISI) in modern communication systems. In this paper, we have modelled a channel and applied output to different equalization techniques like Frequency Flat, Frequency Selective, Decision Feedback and compared their result and found out that the Decision Feedback Equalization is the best one to reduce ISI. In this modelling we have used PSK modulation as a reference for channel modulation technique.
