Abstract
A new approximate technique for evaluating performance of digital fiber-optic systems employing an avalanche photodiode receiver is presented. The essence of the new technique is a point transformation, the normalizing transform, which converts the signal-dependent noise associated with photodetection and avalanche gain fluctuations into signal-independent noise. The new technique is as simple as a Gaussian approximation yet is more accurate.
