摘要：

In this paper, signal processing techniques applied on the received signal from Radio over Fiber system have been investigated. The structure of the RoF system, starting by the 6 0 GHz carrier generation using an external modulator, Optical Single Side Band 1 0 Gb/s QPSK modulation with IQ Dual Parallel Mach Zehnder Modulator, base station, and the electrical coherent receiver is introduced. The performance of the system with attenuation, chromatic dispersion, and frequency offset of the local oscillator at the receiver side is discussed. The frequency domain equalization technique and feedforward carrier recovery algorithm which are used to mitigate the effect of chromatic dispersion on the carrier and the data as well are investigated. Moreover, the proposed solution also covers the frequency offset of the local oscillator at the receiver side. The proposed algorithms are evaluated by simulations run under VPItransmissionMaker environment as well as MATLAB.
