Paper Abstract

The main constraint on applying digital intersymbol interference (ISI) cancellation scheme to high-speed optical receivers is the limited processing speed. A novel ISI cancellation technique is given to relax this limitation by doing ISI cancellation merely for some marginal bits near the decision threshold but not for every bit. The proposed 'Soft Decision ISI cancellation' (SDIC) scheme can operate at a speed much lower than the transmission bit rate. The results show that the SDIC scheme can nearly double the transmission distance at BER equals 10-10, and for fixed distance, it can decrease the BER by three orders.
