Paper Abstract

By applying a Chernoff bound to the error probability of an optically preamplified pulse position modulation (PPM) receiver we are able to present sensitivity results for various length PPM words. In exhibiting a potential sensitivity benefit of 7.1 dB these results compare extremely well to those obtainable from an equivalent on-off keyed non-return to zero (OOK NRZ) system. The results further demonstrate the possibilities of such a receiver configuration by surpassing the fundamental limit of an optically preamplified OOK NRZ receiver and approaching the sensitivity of coherent systems. Additionally a Gaussian approximation is formulated and we compare the Chernoff bound results with those obtainable from the approximation.
