Embodiment Construction
[0043] The present invention will be described in detail below in conjunction with specific experimental examples and accompanying drawings.
[0044] As shown in Figure 1, the components and functions of the central station of full-duplex optical fiber wireless communication are described as follows:
[0045]Data source 1, produces the digital baseband signal of downlink, and radio frequency signal generator 2, produces the radio frequency signal that frequency is fO, electric mixer 3, is used for the digital baseband signal that data source 1 produces and radio frequency signal generator 2 produces The radio frequency signal is mixed to generate electrical millimeter waves. The laser 4 is used to generate a continuous wave laser of a specified wavelength, and the external modulator 5, driven by the electric millimeter wave output from the mixer, modulates the continuous wave laser generated by the laser 4, thereby generating a double-sideband modulation signal, double-sideban...
