Ideal POL-QAM Modulation for Coherent Detection Schemes
01 January 2011
The gain of POL-QAM 6-4 and POL-QAM 2-4 (PS-QPSK) at high OSNR can only be kept at low OSNR by increasing the complexity of the FEC decoder. Consequently DSP effort has to be taken into account for a comprehensive benchmarking of POL-QAM versus PDM-QAM. OCIS codes: (060.2330) Fiber optics communications, (060.4080) Modulation
