【 摘 要 】

References(12)Analog type radio over fiber (RoF) link transports radio frequency (RF) signal composed of different kind of frequency. Although previous papers have reported the transmitting multiple frequency signals using single wavelength without overlapping in electrical frequency domain, this paper assumes seriously contaminated channel for transmitting RF signal so that RF signal locates center frequency in main lobe of baseband (BB) signal. Specifically, this paper proposes RF signal transmission with 10 Gbps optical BB signal. Since RF signal is superimposed onto the optical BB signal, no additional light source is required. In addition, RF signal is naturally bandpass-sampled by random nonuniform sequence, therefore stochastic analysis is required. This paper derives error vector magnitude (EVM) of digitally modulated RF signal when the signal is simply regenerated by using bandpass filter. It is shown that theoretical analysis agrees with experimental results.
