Statistical Eye-Diagram Estimation Method for High-Speed Channel with N-Tap Decision Feedback Equalizer (DFE)

Abstract

In this paper, we propose a statistical eye-diagram estimation method for a high-speed channel including N-tap decision feedback equalizer (DFE). This paper proposes a behavior model for the DFE to replace the DFE in the proposed method. The proposed behavior model fully describes the N-tap DFE, which results in successful eye-diagram estimation with the N-tap DFE. In order to show the effect of the DFE depending on its coefficients, this paper shows the corresponding estimated eye-diagrams. For further analysis on the DFE, we also conducted parametric sweep on the coefficient with the proposed method. For verification, we provide a transient simulation under the same condition. From the comparison, the estimated and simulated eye-diagrams are nearly the same. Therefore, this paper successfully proposes and verifies the statistical eye-diagram estimation method with the N-tap DFE for high-speed serial channels.
