Abstract
Aspects relate to mechanisms for bit-level energy-based probabilistic amplitude shaping. Energy-based encoding operations may be performed on a plurality of information bits in a parallel or hierarchical manner to produce a plurality of amplitude bits. The plurality of amplitude bits may then be mapped to a plurality of symbols to generate a symbol sequence having a non-uniform distribution over constellation points of an alphabet of symbols forming the symbol sequence.
Claims39
An apparatus for wireless communication at a wireless communication device, the apparatus comprising:
- one or more memories;
- and
- one or more processors coupled to the one or more memories, the one or more processors being configured to:
- obtain a plurality of information bits;
- perform an energy-based encoding operation on the plurality of information bits to produce a plurality of amplitude bits;
- and
- map the plurality of amplitude bits to a plurality of symbols to generate a symbol sequence having a non-uniform distribution over constellation points of an alphabet of symbols forming the symbol sequence.
