Paper Abstract

In this paper, we analyse the bit error rate reduction for return-to-zero coding with different duty cycle. It is shown that the optimal design of duty cycle of a given system lies in a compromise between spontaneous emission, intersymbol interferences and interchannel interference. We have carried out the semianalyitic simulations to find the dependence of optimum duty cycle on different system parameters. We found that the optimum duty cycle decreases as the channel spacing increases. For channels without ICI, BER is nearly a constant over a wide range of duty cycle as long as ISI is negligible.
