Several optical AM-PSK partial response signalling (PRS) systems, also known as correlative level signalling, are evaluated through numerical simulation. Discussion is focussed to three-level PRS systems, namely duobinary, modified duobinary and dicode. Suitable transmitter implementation, taking advantage of the phase of the optical wave, allows the use of(More)
