Abstract
The performance evaluation through analytical modeling of virtual carrier-assisted direct-detection single-sideband multi-band orthogonal frequency division multiplexing (MB-OFDM) systems dominantly impaired by amplified spontaneous emission noise is presented. An analytical expression is obtained for the bit error ratio (BER) of these systems, using the analytical relationship between the electrical signal-to-noise ratio and the optical signal-to-noise ratio. In order to analyse the accuracy of the analytical expression, the BER estimates provided by the analytical model are compared with the ones obtained using numerical simulation and the exhaustive Gaussian approach. Excellent agreement between the BER estimates is verified when distortion does not affect significantly the performance of the MB-OFDM signal.
