Abstract:
The use of digital transmission with narrow light pulses appears attractive for data communications, but carries with it a stringent requirement on system bit timing. In this paper we investigate the effects of imperfect timing in a direct detection (noncoherent) optical system using PPM bits. Particular emphasis is placed on specification of timing accuracy, and an examination of system degradation when this accuracy is not attained. Bit error probabilities are shown as a function of timing errors, from which average error probabilities can be computed for specific synchronization methods. Of significant importance is the presence of a residual, or irreducible error probability, due entirely to the timing system, that cannot be overcome by the data channel.
