Abstract:
1. A method of binary coded data communication comprising: providing a transmitter having a turbo trellis coded modulator (TTCM) encoder and constellation shaping elements; dividing a desired symbol sequence into a first part having K-bits, a second part having N*k-bits, and a third part having the remaining bits; processing the first part of the desired symbol sequence via a shell mapper to generate N shells; processing the second part of the desired symbol sequence via the TTCM encoder to generate N cosets; mapping the third part of the desired symbol sequence, the N shells, and the N cosets to generate N transmit symbols, wherein N, K, and k are integers; providing a receiver having a receiver turbo decoder and receiver constellation shaping elements; and using the receiver turbo decoder and the receiver constellation shaping elements to process the N transmit symbols to recover the desired symbol sequence wherein the step of
