Title:
VIRTUAL LOOKUP TABLE FOR PROBABILISTIC CONSTELLATION SHAPING
Document Type and Number:
WIPO Patent Application WO/2019/029529
Kind Code:
A1
Abstract:
Probabilistic generation and decoding modulation symbols for use with optical communication. Codewords are generated using combinations of symbols from a modulation symbol alphabet, and each type of modulation symbol is sequentially generated using a hardware efficient combination generator that performs as a virtual lookup table (LUT). Likewise, decoding can be performed by sequentially identifying locations of individual modulation symbols within the received codeword.
