We propose a novel coded modulation scheme for coherent optical orthogonal frequency-division multiplexing (CO-OFDM) to achieve high-speed transmission at spectral-efficiencies near the Shannon limit. The proposed coding scheme relies on the concept of bit interleaved coded modulation with iterative decoding (BICM-ID), low-density parity-check (LDPC) codes, and shaped iterative polar modulation (IPM). To further increase the transmission spectral efficiency, reduced guard interval (RGI) CO-OFDM… CONTINUE READING
