2、it pulse responses(LFPR)from a PAM4 pattern waveform is introduced in 1.The multiple LFPR hold more detailed information of the signal that can be used to optimize DFE taps for an enhanced DFE structure.This paper introduces this novel DFE structure called multiple pulses-based DFE(MPDFE).The MPDFE

3、is compared with the traditional DFE that is based on the single LFPR,and the Maximum-likelihood sequence estimation(MLSE)equalizers on the PAM4 signals.Author(s)Biography Kan Tan is a Principal Engineer at Tektronix.He has worked on DSP for performance scopes;signal integrity analysis such as jitte
