Abstract
A wireless communication apparatus and method using probabilistic constellation shaping in connection with modulation. A wireless transmission device may determine a sequence of amplitude symbols from a sequence of information bits using a distribution matcher (DM) configured for probabilistic amplitude shaping. The device may further apply error correction coding to encode an information block corresponding to at least a portion of the sequence of amplitude symbols. And the device may generate a sequence of output symbols for transmission based on the encoded information block. The device may apply interleaving to one or more of the sequence of 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.
