High Speed and Cost Efficient Adaptive Equalizer for ISI Removal

摘要

This paper includes an efficient approach to design and implement a high speed and area efficient Adaptive Equalizer with LMS algorithm for ISI removal. In telecommunication, Intersymbol interference (ISI) is caused by multipath propagation. Therefore, the main aim is of designing the transmitter and receiver is to minimize the effects of intersymbol interference. Here output of the model is compared for different values of (step size) of LMS algorithm. Then the proposed model is synthesized with ISE 10.1, simulated with Modelsim and implemented on Virtex2 based xc2vp30-7ff896 target device. The result shows that algorithm with 0.005 step size has best constellation diagram and less MSE value than the step size of 0.001. The proposed model has the advantages of reduction in ISI using simple and less computational complex LMS algorithm along with enhanced performance in terms of speed, cost and area with existing results.
