Title:
MIXED SCHEME FOR ACCURATE APPROXIMATIONS IN CONSTELLATION SHAPING
Document Type and Number:
WIPO Patent Application WO/2024/026614
Kind Code:
A1
Abstract:
Certain aspects of the present disclosure provide a method for wireless communications. The method generally includes obtaining a sequence of information bits, applying a shaper algorithm to the sequence of information bits to generate a sequence of shaped symbols, wherein the shaper algorithm involves at least one parameter that indicates a quantity of symbol sequences that satisfies an energy constraint and further wherein the application of the shaper algorithm comprises determining, for a given energy value and a symbol sequence length, whether to use an approximation or a stored value of the at least one parameter, and outputting the sequence of shaped symbols for transmission.
