Performance of probabilistic amplitude shaping with BICM‐ID

Electronics Letters, 2021
It is numerically shown that bit error rate (BER) performance of probabilistic amplitude shaping (PAS) applying a bit‐to‐symbol mapping of non‐Gray natural binary code assigned to 64‐quadrature amplitude modulation is significantly improved by bit ...
