Abstract :
A receiver with soft decision intersymbol interference (ISI) cancellation (SDIC) is presented to deal with ISI 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 ISI cancellation circuit to operate with a processing and propagation delay much longer than 1-b period. Therefore, it is very promising in very-high-bit-rate optical systems
