Abstract :
We have proposed a novel radio-over-fiber (ROF) architecture to reduce the system cost at both central office (CO) and base station (US). In this architecture, by incorporating the proper DC bias and optical filtering techniques in CO, the optical millimeter-wave (mm-wave) carriers are generated with four times frequency of the local oscillator (LO) signal. The BS is simplified by using the separated optical carrier along with downlink mm-wave signals to carry the upstream data.
