1. A wireless communication device, comprising:
a processing system that includes one or more processors and one or more memories coupled with the one or more processors, the processing system configured to cause the wireless communication device to:
perform a first non-binary polar transformation encoding operation on a first symbol vector, including a set of data symbols, that generates a second symbol vector including a set of transformed data symbols, the set of data symbols being associated with first locations associated with the first non-binary polar transformation encoding operation;
perform a non-binary polar transformation decoding operation on the second symbol vector, in accordance with a set of probability values associated with a set of amplitude shaping target values, that generates a third symbol vector including a first set of shaping symbols;
perform a second non-binary polar transformation encoding operation on the third symbol vector that generates a fourth symbol vector including a second set of shaping symbols, the second set of shaping symbols being associated with second locations associated with the second non-binary polar transformation encoding operation; and
transmit a signal that is modulated in accordance with a fifth symbol vector including a set of shaped symbols associated with a combination of the second symbol vector and the fourth symbol vector.
