Efficient Designing of Communication Link with PSK Modulation using Adaptive Equalization

In the era of revolution of communication, bandwidth is definitely one of the scarier thing. So the pressure is to reduce the requirement of bandwidth while reduction in bandwidth may result in Inter Symbol Interference. One of the ways to reduce Inter Symbol Interference is to use equalization and in this paper, we have proposed decision feedback equalizer with adaptive equalization for reducing inter-symbol interference and from the depicted results it it quite obvious that the ISI reduces drastically by using adaptive equalization.
