Abstract:
A system/method for data transport, including encoding one or more streams of input data using one or more Low Density Parity Check (LDPC) encoders; employing one or more signal constellations obtained using an optimum signal constellation design (OSCD); determining an optimum mapping rule by comparing cost functions of each of a plurality of mapping rules; combining one or more LDPC-coded OSCD signal constellation data streams with coherent optical-orthogonal frequency division multiplexing (CO-OFDM) coded modulation to achieve channel capacity; and mode-multiplexing and transmitting one or more independent LDPC-coded optimum signal constellation design (OSCD) data streams over a transmission medium.
