Abstract

Two approaches for Modifying the performance of asymmetrically-clipped optical orthogonal frequency-division multiplexing (ACO-OFDM) technique are proposed. These two approaches involve the use of unipolar encoding which facilitates transmission through optical channels. Monte Carlo simulations have been carried out for the proposed system to evaluate its bit error rate (BER) performance. Our simulation results are then compared to that of both conventional ACO-OFDM and bipolar OFDM systems. It turned out that the proposed modifications improve the BER performance when compared to that of traditional systems. Specifically, in case of the first approach the performance of ACO-OFDM scheme can be improved by more than 3 dB when adopting the proposed modifications. In addition these modifications would eliminate the reduction in the BER performance between ACO-OFDM and bipolar OFDM and surpass its performance.
