| Abstract: | It is well known that the atmospheric multipath fading is the main cause of circuit interruption in radio microwave digital communication.One of the combating methods is the use of adap- tive transversal equalizers.In this paper we analyse the perfor- mance of a advanced Decision Feedback Equalizer with a new idea,that is the tap weights which are controlled by MSE with adaptive coefficients,and sampling method instead of multi- pliers.The simulation and laboratory results prove these attractive performance in these modifications. |
