ABSTRACT:
An optical receiver including a plurality of time delay elements and threshold decision elements configured to receive a signal representative of an optical signal. Each of the time delay elements is configured to impart an associated time delay to the signal. Each of the threshold decision elements is configured to compare the signal to a plurality of threshold levels. Each decision element outputs a signal indicative of a probability that a particular pulse of the received signal is a binary one at its associated sampling time. An optical communication system and a method of detecting a received data signal in an optical communication system are also provided.
