Description

technical field

[0001] The invention is a wireless communication relay transmission technology, which is applicable to the wireless communication relay transmission of conventional wireless communication systems, and belongs to the technical field of wireless communication. Background technique

[0002] In the currently applied optical fiber wireless relay system, fiber optic direct relay technology is widely used, and its system structure is usually in the form of a near-end machine connected to one or more remote machines through optical fiber lines. The wireless communication relay and forwarding function can be realized between the end machines. The working method is that the near end machine converts the wireless received signal into an optical signal and transmits it to the far end machine through an optical fiber, and then restores it into an electrical signal and sends it out in the same frequency mode. The end machine converts the wireless received signal into an op...
