Eye diagram reconstruction using asynchronous imperfect sampling, application to ber estimation for fiber-optic communication systems
In this paper we present a new and robust method to construct the eye diagram from asynchronous samples of a digital communication signal. No a priori knowledge of the bit period is needed. The method uses an approach based on periodogram estimation which is suitable even for (highly) under-sampled signals. Random shifts due to clock errors are also being corrected. We apply this method to the Bit Error Rate estimation of an optical signal in an experimental setup.
