Experimental verification of 64-Gbd/64-QAM interworking of probabilistic shaping with a digital resolution enhancer
2021 OPTICAL FIBER COMMUNICATIONS CONFERENCE AND EXPOSITION (OFC)(2021)
摘要
We present an experimental study of probabilistic constellation shaping gains in low resolution digital-to-analogue converter based transceivers, which utilizes digital resolution enhancement. A SNR gain of 0.65dB for optimized probabilistic shaping factors can be achieved.
