Popis: | Band-trellis enumerative sphere shaping is proposed to decrease the energy variations in channel input sequences. Against sphere shaping, 0.74 dB SNR gain and up to 9% increase in data rates are demonstrated for single-span systems. Comment: 3 pages, 4 figures, accepted to be presented at the OFC 2022, a few numeric typos are corrected (v2: a typo in the caption of Fig. 4 is fixed) |
