摘要：

In this paper, we have proposed a multiband multimode ROF system which is experimentally demonstrated with the simultaneous generation and transmission of the CDMA (f(0)=830MHz), WCDMA (f(0)=1950mHz) and WIMAX (f(0)=2400MHz) signals. The dependence of the static nonlinear properties of the system on the applied signals has been discussed to illustrate the necessity for extracting the static nonlinear properties in real time when the real modulated signals are applied. The dynamic exponential weighted moving average method is used to extract the static nonlinear properties of the multiband multimode ROF system which consist of the AM/AM and AM/PM characteristics. The spectrum of the input signal is compared with the spectrum of the output signal to illustrate the nonlinear distortion in frequency domain.
