Paper Abstract

A simple frequency domain pilot interval allocation scheme is proposed for pilot-based channel estimation of a compatible single-sideband modulation direct detection optical orthogonal frequency division multiplexing transmission system. Compatible single-sideband modulation for orthogonal frequency-division multiplexing transmission with direct detection is strongly suggested to overcome chromatic dispersion without explicit dispersion compensation. The proposed optimal scheme can improve the channel estimation performance, by approximately three dB receiving sensitivity, without additional hardware or complex computation.
