Multipath Interference Mitigation for PAM4 Transmission Based on Spectrum Inversion and RRC Filtering
We have developed an efficient multipath interference (MPI) mitigation method based on spectrum inversion and root-raised cosine filtering. Simulations have verified that this scheme has advantages over the traditional high-pass filtering scheme in suppressing MPI and improving system BER performance for large linewidth lasers.
