Popis: Due to the stimulating success in developing optical amplifiers, intersymbol interference (ISI) will become the domi- nant limit on both bit rate and transmission distance in long-haul optical fiber communication systems. Here we present a receiver with "Soft Decision IS1 Cancellation" (SDIC) to deal with IS1 in high-speed lightwave systems. The analytical and simulation results show that the transmission distance can be doubled with SDIC. In addition, the receiver with SDIC allows the IS1 cancellation circuit operating with processing and propagation delay much longer than 1-b period. Therefore, it is very promising in very high bit rate optical systems.
