Abstract
An analytical model (AM) for performance evaluation of distortion-impaired direct-detection single-sideband
optical orthogonal frequency-division multiplexing systems employing virtual-carriers (VCs) is presented. The
error vector magnitude (EVM) is used as figure of merit for performance evaluation, and the effectiveness of the
AM is verified through comparison of its EVM estimates with the ones obtained using numerical simulation
(NS). Discrepancies between the EVM estimates of the AM and NS not exceeding 1 dB are verified for a VC to
band power ratio of 12 dB and for VC to band gaps exceeding half of the signal bandwidth.
