Rate Adaptive Autoencoder-based Geometric Constellation Shaping

Signal Processing 2023-01-04 v1

Abstract

An autoencoder is used to optimize bit-to-symbol mappings for geometric constellation shaping. The mappings allow for net rate adaptivity without additional hardware complexity, while achieving up to 300km of transmission distance compared to uniform QAM.
