Abstract :
In this letter, a novel linear frequency-domain compensation (FDC) of the resonant cavity light emitting diode (RC-LED) for discrete multi-tone (DMT) modulation has been used for the first time in the nonlinearity mitigation of step-index polymer optical fiber (SI-POF) communication systems. The proposed FDC method can be easily implemented in any multi-carrier communication system. Compared with the classical DMT scheme, FDC DMT benefits from higher power efficiency in terms of clipping for peak-to-average power ratio reduction. Two SI-POF experimental setups with different 3 dB POF bandwidths are built with the same RC-LED. Under the same experimental conditions, a higher transmission rate has been achieved with the proposed FDC DMT method compared with classical DMT at the same bit error rate level.
