Experimental Evaluation of Coded Modulation for a Coherent PDM System with High Spectral Efficiency
04 March 2012
We experimentally evaluate the performance of optimized constellation labelings together with soft-FEC decoding based on low-density parity-check codes in a coherent burstmode PDM system with spectral efficiency of 12 bit/channel use. OCIS codes: (000.0000) General; (000.0000) General [8-pt. type. For codes, see www.opticsinfobase.org/submit/ocis.]
