Abstract :
Simulation results are presented showing the behavior of the error-vector-magnitude and symbol-error rate under distortion conditions for OFDM signals with different IFFT sizes and modulation level, and smoothness of the nonlinearity. While more generally applicable, the results presented consider practical design goals for radio-over-fiber (RoF) links which need to impart minimum performance degradation on the transported signals.
