Paper Abstract

We propose and simulate a single-side band (SSB) Radio-over-Fiber ( RoF ) system based on OFDM-MSK modulation. In-phase/quadrature-phase (IQ) imbalance effect can significantly degrade the system performance. In order to obtain a better system performance, at the transmitter, the phase departure tolerance should be within 1 degree and the amplitude departure tolerance should be within 5% in the electrical domain, the phase departure tolerance should be within 10 degrees and the amplitude departure tolerance should be within 40% in the optical domain, the departure tolerance of splitting ratio should be within ±12%, and at the same time, time misalignment should be within ±32ps. At the receiver, the phase departure tolerance should be within 2 degrees and the amplitude departure tolerance should be within 10%. Furthermore, it's further found that the electrical part of the transmitter presents a stricter requirement on the IQ balance than the receiver, while the receiver presents a stricter requirement on the IQ balance than the optical part of the transmitter.
