We discuss the use and the interpretation of the information rate as a performance evaluation tool for optical communication systems. In particular, we obtain insights on the impact of the receiver structure on the ultimate achievable performance limits.
We investigate an MLSD-based optical receiver which enables effective detection of DPSK with only one photo-diode and without delay interferometer. The system exploits the uncompensated chromatic dispersion to deliver robust and reliable data detection.
We investigate the impact of state-complexity reduction on the performance of maximum likelihood sequence detection (MLSD) receivers for direct-photodetection long-haul optical communication systems affected by uncompensated chromatic dispersion (CD). We directly compare two possible approaches: (i) detection through a simple ldquobrute-forcerdquo state-complexity reduction strategy and (ii) a more...
