1. A method of wireless communication, comprising:
segmenting an input sequence into a first sequence of information bits and a second sequence of information bits;
determining a sequence of amplitude symbols from the first sequence of information bits using a distribution matcher configured for probabilistic amplitude shaping;
combining the second sequence of information bits and a sequence of binary symbols corresponding to at least one portion of the sequence of amplitude symbols to form an information block;
applying error correction coding to encode the information block;
generating a sequence of output symbols based on the encoded information block; and
applying interleaving to one or more of the sequence of amplitude symbols, a sequence of encoded amplitude symbols, the information block, the encoded information block, or a combination of the sequence of amplitude symbols and the encoded information block, for the generating of the sequence of output symbols.
