Abstract
In this paper, we propose an efficient architectural design for Adaptive Decision Feedback Equalizer (ADFE) for high-speed reliable data transmission through wired as well as wireless communication channels to minimize Inter Symbol Interference (ISI). High hardware cost of the system makes an urge to redesign it in order to minimize overall circuit complexity and cost. Realization of CORDIC based pipelined ADFE architecture using reformulated LMS algorithm has not only reduced multipliers in its feed forward path, the flexibility and modularity of the components makes it possible for easy implementation also. The realization results area efficient, high speed and throughput with good convergence. The efficacy of the proposed equalizer is corroborated with MATLAB simulations for mitigation of severe channel distortion arise due to ISI in high speed communication systems.
