Abstract
A sparse nonlinear weighted DFE (S-NWDFE) is proposed for a 520-Mbps PAM-4 blue-LED-based 2-m UWOC system, reducing the number of kernels by 44.4% while achieving comparable (superior) equalization performance compared to the NWDFE (VDFE). Compared with S-VDFE, the S-NWDFE requires at least 20% fewer kernels at the same data rate.
