Problems solved by technology

[0003] However, in the data transmission mode between the repeater and RRU, the SNR (signal-to-noise ratio) drops seriously, and the repeater and RRU also interfere with each other, especially the edge users between the two, the interference is more serious
Secondly, if the second jump is performed through the repeater, the SNR will further deteriorate, resulting in further degradation of the demodulation performance of the signal
[0004] In addition, in the indoor distribution scene, through wireless relay, under objective conditions such as floor partition and wall blocking, direct coverage cannot be performed through external wireless nodes

Abstract

The embodiment of the invention provides an optical fiber distributed system. The optical fiber distributed system comprises a radio remote unit (RRU), an access unit and a coverage unit, wherein one end of the access unit is connected with an antenna of the RRU through a wired feeder line; the other end of the access unit is connected with the coverage unit through a composite optical cable; and the access unit is used for converting the data sent by the RRU into a digital signal, processing the digital signal according to the frame structure and data arrangement of the digital signal, and sending the processed digital signal to the coverage unit. According to the optical fiber distributed system provided by the embodiment of the invention, the coverage range is enhanced, indoor distribution coverage and other scenes are realized, and the problem of deep coverage is solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an optical fiber distributed system. Background technique [0002] A wireless communication system usually includes a base station and a remote radio unit (Remote Radio Unit, referred to as "RRU"). In the data transmission based on the wireless communication system, due to the limitation of a long transmission distance, the data transmission performance is poor. Therefore, A repeater as a relay node is added in the wireless communication system. figure 1 It is a schematic diagram of data transmission based on a wireless communication system in the prior art, such as figure 1 As shown, in the prior art, the repeater as a relay node and the wireless signal between the relayed RRU are used for data transmission, and then the repeater is used for coverage to expand the coverage. Multiple repeaters can be deployed within the coverage of the RRU, or the repeater can perform one...
