Adaptive Equalization of Fractionally Spaced Equalizer Based on Activity Detection and Tap Decoupling

In this paper, we presents an adaptive equalization of fractionally spaced equalizer based on activity detection and tap decoupling. Fractionally-Spaced equalizer (FSE) with Activity Detection improves the stability, steady- state error performance and convergence rate of the system. Implementation of the FSE technique provide alternative to linear equalization. The objective of the FS equalizer is to minimize the bit error rate of the data due to the disturbances of noise and intersymbol interference phenomenon on the channel of the digital communication system. Results indicates that FSE with activity detection showed considerable improvement in convergence rate over the fractionally spaced without activity detection. Finally, convergence rate indicate that this FSE technique perform the equalization task with great accuracy and with less time consumption.
