Spectrally efficient four-dimensional modulation
Paper in proceeding, 2012
We quantify the performance of regular four-dimensional constellations with high spectral efficiency, and compare the sensitivity gain relative to rectangular QAM. Gains up to 1.51 and 1.97 dB over the corresponding QAM formats can be achieved.
