Abstract :
We propose quaternary block coded high-dimensional modulation formats and compare them to spherical lattice-cut and hybrid modulation formats. Noise tolerance and transmission performance are simulated for spectral efficiencies ranging between those of DP-QPSK and DP-8QAM. Similar performance to sphere-cutting is attained with lower DAC resolution.
