Energy based splitting and combining for probabilistic amplitude shaping based communication

A receiver device for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• receive a symbol sequence that conveys a plurality of information bits;
• determine a prefix subsequence and a postfix subsequence based at least in part on the symbol sequence;
• perform a first decoding operation on the prefix subsequence to determine a first integer;
• perform a second decoding operation on the postfix subsequence to determine a second integer;
• perform a third decoding operation on the first integer and the second integer to determine a third integer, the third decoding operation being associated with an alphabet, a sequence length, and an energy threshold, and to perform the third decoding operation, the one or more processors being configured to:
• determine a shifted third integer based at least in part on the second integer and the third integer, and
• determine the third integer based at least in part on the shifted third integer, a prefix subsequence energy, a prefix subsequence length, the sequence length, and the energy threshold;
• and
• recover the plurality of information bits associated with a set of integers, the set of integers including the first integer, the second integer, and the third integer.
