Low-Complexity, Loop-Unrolled Decision-Feedback Equalizer for IM/DD System Using PAM Formats (Th1A.44)

Presenter: Yukui Yu, KAIST, Korea

We propose and demonstrate a low-complexity, loop-unrolled DFE for band-limited IM/DD system. The proposed equalizer nearly doubles the maximum achievable data-rate of DFE for PAM-4 signal, but requires complexity similar to that of NRZ DFE.
