摘要：

In this letter, we conceive a multilayered coding scheme for the recently proposed layered asymmetrically clipped optical orthogonal frequency division multiplexing (LACO-OFDM) system, which exploits its layered structure for protecting the information bits transmitted in the base layer. Explicitly, we intrinsically integrate error correction into the layered structure of the LACO-OFDM system and invoke soft iterative decoding between the layers at the receiver. Our system operates within 2 dB of the capacity limit at a bit error ratio of 10(-4).
