Abstract:
A digital communication system, having a transmitter to transmit a digital signal; and a receiver to receive the digital signal; wherein the digital signal utilizes a 32APSK system with FEC coding, and the signal is bit-mapped using gray mapping, and bits of the digital signal are ordered based on the values of a log likelihood ratio from a communications channel.
