Probabilistic Shaping and Non-Binary Codes
Published 27 Jan 2017 in cs.IT and math.IT | (1701.07976v1)
Abstract: We generalize probabilistic amplitude shaping (PAS) with binary codes to the case of non-binary codes defined over prime finite fields. Firstly, we introduce probabilistic shaping via time sharing where shaping applies to information symbols only. Then, we design circular quadrature amplitude modulations (CQAM) that allow to directly generalize PAS to prime finite fields with full shaping.
