Abstract

For high-speed train communication system, broadband analog radio-over-fiber based backhaul networks with a centralized processing unit can reduce hard hand-over processes by prediction of train location and be tracking the train by adaptive optical path routing. In the system, an automatic bias control technique without any dither signals is important to avoid the degradation of the throughput. In the study, we design and demonstrate a single-sideband optical modulation using an optical IQ modulator.
