End-to-End Learning of Joint Geometric and Probabilistic Constellation Shaping

9 Dec 2021 · Vahid Aref, Mathieu Chagnon ·

We present a novel autoencoder-based learning of joint geometric and probabilistic constellation shaping for coded-modulation systems. It can maximize either the mutual information (for symbol-metric decoding) or the generalized mutual information (for bit-metric decoding).
