Abstract
This disclosure describes systems, methods, and devices related to fixed-to-fixed shaping encoding. A device may determine a mapping table associated with uniformly distributed bits into amplitudes with desired probabilities. The device may predict a number of output bits for an input block. The device may apply padding as needed based on the predicted number of output bits.
