摘要：
Original analysis and results are given for an optically preamplified digital pulse-position-modulation (PPM) receiver with an improved electrical-domain filtering regime consisting of a matched filter cascaded with a pulse-shaping network. Impressive sensitivity results are reported, with the 21.54 photons/bit predicted at 622 Mbit/s, surpassing both an equivalent optically preamplified on-off keyed nonreturn-to-zero (OOK NRZ) system (by 8.1 dB) and the fundamental limit of such a preamplified OOK NRZ receiver.
