Coherent fiber-optic microcellular radio communication system using a novel RF-to-optic conversion scheme

In this system a radio signal is converted into an optical signal with the same modulation format coherently transmitted through a wide-band optical fiber without any baseband demodulation and modulation. The theoretical analysis and computer simulation of transmission performances of radio QPSK and QAM signals clarify that the proposed system is superior to the fiber-optic radio communication system using conventional coherent analog optical links.<
