Abstract
This disclosure describes systems, methods, and devices related to enhanced constellation shaping. A device may generate payload bits associated with a frame, wherein the payload bits comprise a first portion and a second portion. The device may send the first portion of the payload bits through a shaping encoder. The device may generate shaped bits from the shaping encoder. The device may determine a number of amplitude bits based on the shaped bits. The device may generate parity bits from the shaped bits and the second portion going through an low-density parity-check (LDPC) encoder. The device may select sign bits comprising the second portion and a first subset of the parity bits. The device may send the amplitude bits with the sign bits to a modulator before transmitting the frame to a first station device.
