Optical fiber wireless integrated system

The invention provides an optical fiber wireless integrated system which comprises an optical baseband signal generation module, a millimeter wave wireless signal generation module, an electro-optic conversion module and an optical signal detection module. The optical baseband signal generation module is located in a central station of a transmitting terminal, modulates OFDM signals on first local oscillator optical signals and conducts PM operation, so that first optical baseband signals of PM-OFDM are formed; the millimeter wave wireless signal generation module conducts heterodyne beat coherent detection on the first optical baseband signals of PM-OFDM and second local oscillator optical signals, so that millimeter wave wireless signals are acquired and sent wirelessly; the electro-optic conversion module modulates the received millimeter wave wireless signals on third local oscillator optical signals, so that second optical baseband signals of PM-OFDM are formed; the optical signal detection module conducts homodyne coherent detection on the second optical baseband signals of PM-OFDM and fourth local oscillator optical signals, so that the OFDM signals are acquired.
