Multi-class coded layered asymmetrically clipped optical OFDM
Multi-class coded layered asymmetrically clipped optical OFDM
Multi-class channel coded layered asymmetrically clipped optical orthogonal frequency division multiplexing (LACO-OFDM) is proposed, where the achievable rate of the system is derived based on our mutual information analysis. We conceive a multi-class channel encoding scheme integrated with the layered transmitter. At the receiver both the coded and uncoded likelihood ratios (LLRs) are extracted for inter-layer interference cancellation and symbol detection, respectively. Simulations are conducted and the results show that our design approaches the achievable rate within 1.1 dB for 16QAM 4-layer LACO-OFDM with the aid of a half-rate 8-iteration turbo code at BER=10-3, outperforming its conventional counterpart by about 3.6 dB.

Abstract
Multi-class channel coded layered asymmetrically clipped optical orthogonal frequency division multiplexing (LACO-OFDM) is proposed, where the achievable rate of the system is derived based on our mutual information analysis. We conceive a multi-class channel encoding scheme integrated with the layered transmitter. At the receiver both the coded and uncoded likelihood ratios (LLRs) are extracted for inter-layer interference cancellation and symbol detection, respectively. Simulations are conducted and the results show that our design approaches the achievable rate within 1.1 dB for 16QAM 4-layer LACO-OFDM with the aid of a half-rate 8-iteration turbo code at BER=10-3, outperforming its conventional counterpart by about 3.6 dB.
