Title:
ENERGY-BASED PROBABILISTIC AMPLITUDE SHAPING
Document Type and Number:
WIPO Patent Application WO/2024/045110
Kind Code:
A1
Abstract:
This disclosure provides methods, devices and systems for encoding data for wireless communication to achieve an amplitude distribution. One implementation includes a method in which probabilistic amplitude shaping is constrained by a maximum energy and a sequence length, and encoding iterations select energy transition values based on transition probabilities. Another implementation includes a method in which probabilistic amplitude shaping has a first step that defines a specific energy of an output sequence and uses subsequent encoding iterations to select energy transition values based on transition probabilities and within the specific energy. The methods generate output sequences defining amplitude symbols that are used to encode data for transmission.
