Abstract

The invention relates to a combiner, a combing device and a signal combing system, wherein the combiner comprises a first duplexer, a second duplexer and a bridge. The first duplexer is provided with an output terminal connected with two base stations respectively, and is used for receiving primary upstream signals and outputting the primary upstream signals into the two base stations respectively; the second duplexer is provided with an output terminal connected with two base stations respectively, and is used for receiving branch upstream signals and outputting the branch upstream signals into the two base stations respectively; the bridge is provided with an input terminal connected with the two base stations respectively, and an output terminal connected with an antenna, and is used for receiving downstream signals from the two base stations and transmitting to the antenna. Compared with the prior art, a classification receiving manner is adopted for upstream signals, that is, two paths of upstream signals are amplified at the same time, then uploaded to the base stations, and analyzed by the base stations, so that the receiving accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a combiner, a combiner and a signal combiner system. Background technique [0002] A repeater is a relay transponder between a base station (BS) and a mobile station (MS). It belongs to the same-frequency amplification device and refers to a radio transmission relay device that enhances the signal during wireless communication transmission. The basic function of the repeater is a radio frequency signal power booster. The optical fiber repeater is a repeater that uses optical fiber for signal transmission. It uses the characteristics of small optical fiber transmission loss, convenient wiring, and is suitable for long-distance transmission. It can solve the problems of villages and towns, tourist areas, highways, etc. Signal coverage in large and super-large buildings, used in large-scale high-rise buildings (groups), residential areas and other occasions with high requirem...
