  • Publication number: 20250150320
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may perform, on a set of information bits, a distribution matching procedure to obtain a distributed amplitude symbol sequence. In some cases, the wireless device may perform the distribution matching procedure using approximations of quantities of distributed amplitude symbol sequences that each have a same length and a same transmission energy. The wireless device may then encode the distributed amplitude symbol sequence and transmit the encoded distributed amplitude sequence. A device that receives the encoded distributed amplitude sequence may perform a distribution dematching procedure on the distributed amplitude sequence based on approximating quantities of distributed amplitude symbol sequences.
