1. A method for wireless communication by a wireless communication device, the method comprising:
generating a plurality of data units, each data unit including information bits;
performing a prefix encoding operation on the information bits in the plurality of data units that generates one or more output bitstreams including amplitude bits for each of the data units based on the information bits in the data units, the performance of the prefix encoding operation including comparing sequences of consecutive bits of the information bits to one or more patterns of bit values of a set of patterns of bit values, each pattern of bit values of the set of patterns of bit values being associated with a respective sequence of amplitude bits of a set of sequences of amplitude bits, each sequence of amplitude bits of the set of sequences of amplitude bits being associated with a respective symbol amplitude of a set of symbol amplitudes, a number of patterns of bit values in the set of patterns of bit values being less than a number of sequences of amplitude bits in the set of sequences of amplitude bits;
identifying a boundary in the information bits;
inserting, into the one or more output bitstreams, based on the identified boundary, a sequence of amplitude bits of the set of sequences of amplitude bits that is not associated with any of the patterns of bit values of the set of patterns of bit values, the inserted sequence of amplitude bits indicating the boundary; and
transmitting a wireless packet including a plurality of symbols based on the one or more output bitstreams.
