Problems solved by technology

[0012] Although the 3dB bridge common-antenna feeder network is simple, due to the device characteristics of the 3dB bridge itself, it is determined that the forward and reverse of this networking method will have a loss of more than 3.0dB, which has a greater impact on forward coverage and reverse reception. big impact

Embodiment Construction

[0034] The present invention provides a common antenna feed method and system, the core idea of ​​which is: 1) the transmit signal is coupled by a coupler and then transmitted to the duplexer, and then transmitted to the antenna along the feeder; 2) the received signal is transmitted from the antenna to the duplexer along the feeder Workers, and transmitted to the base transceiver station after power distribution.

[0035] The single-transmission and double-reception of the present invention refers to two antennas (a pair of dual-polarized antennas) of the same sector in the communication system, one of which is shared by sending and receiving, and the other is only used for diversity reception; It means that the two antennas in the same sector share the same transmission and reception. The base transceiver station of the present invention may be provided by different equipment vendors.

[0036] The present invention relates to the following components: a duplexer (Duplexer),...

Abstract

The invention discloses a common antenna feed method and system. The common-antenna feeding method includes: 1) transmitting the signal to the duplexer after being coupled by a coupler, and transmitting it to the antenna along the feeder; 2) transmitting the received signal from the antenna to the duplexer along the feeder line, and transmitting it after power distribution to the base transceiver station. The common antenna feed system includes a base station transceiver, a feeder and an antenna, and also includes: a coupler, a duplexer and a power splitter; the coupler transmits the transmitted signal to the duplexer after coupling, and transmits it to the antenna along the feeder; The duplexer is used to separate the transmitted and received signals. When the received signal is transmitted from the antenna to the duplexer along the feeder, it is transmitted to the power divider; the power divider divides the power of the received signal and transmits it to the base transceiver station. The present invention can support different devices in the same system to share antenna feeds, and reduce link loss.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for sharing antennas in the same system. Background technique [0002] In a communication network, a Base Station Transceiver (BTS) transmits and receives signals through an antenna feeder system. Shared antenna feeder means that BTS share a set of antenna feeder system, which can save equipment costs and improve overall benefits. Common antenna feeder can be divided into two ways, one is different system common antenna feeder, such as global system for mobile communication GSM (global system for mobile communication) and wideband code division multiple access WCDMA (Wideband Code Division Multiple Access) common antenna feeder ; One is the common antenna feeder of the same system, such as code division multiple access CDMA (Code Division Multiple Access) 800M 1X and CDMA800M DO common antenna feeder. The antenna-feed sharing solution for diff...
