[0034] Detailed description of the new photon probability mapping process based on terrace formation
[0035] The process of performing photon probability mapping on the QAM constellation points after the Gaussian beam is terraced in the present invention is as follows: figure 1 shown. In the figure, the 64QAM modulation format is taken as an example. Gaussian beams are regulated by two-level terraced gradients to generate new beams, and then the new beams are used to modulate binary data into 64 points in the QAM constellation diagram.
[0036] The system components of a new photon probability mapping method based on terraced field forming in the present invention mainly include the following modules: probability matcher, Gaussian beam generation, spatial phase array, constellation mapping data projection, centralized convergence emission, photon signal pre-emphasi...
