Comparison of uniform cross QAM and probabilistically shaped QAM formats under the impact of transmitter impairments

• Considering the nonideal response of Mach-Zehnder modulators, uniform cross QAM constellations improve upon probabilistically shaped QAM by a factor of up to 4 in uncoded symbol error rate and also offer higher achievable information rates, at the same source entropy and optimal electrical signal powers.
