Embodiment Construction
[0024] The solution of the present invention will be described in further detail below with reference to the accompanying drawings.
[0025] The scheme principle of the present invention is as follows figure 1 shown. The implementation here is exemplified by a two-element beamforming system using LP01 and LP02 modes of transmission. At the central office, the ASE light source is narrow-band filtered with an optical filter. The narrow-band filtered ASE light source is amplified by an optical amplifier and injected into the intensity modulator. The radio frequency signal to be modulated is modulated on the ASE optical carrier, amplified again by the optical amplifier, and split into a first delay copy signal and a second delay copy signal by a 1*2 coupler. After the first time-delayed copy signal passes through the adjustable optical attenuator and the adjustable optical delay line, the mode multiplexer is used to inject the LP01 mode of the few-mode fiber and transmit to the...
