Embodiment example 1

[0031]Implementation case 1: When one near-end unit has one remote unit, no power distribution device needs to be added, and the near-end unit and the remote unit are connected through a feeder. The near-end unit is placed on the side close to the signal source, and the remote unit is placed at each coverage point. see figure 1 As shown in the following behavior example, the two signals coupled by the MIMO base station T100 through the couplers T102 and T103 are combined into one signal by the near-end unit T104, and transmitted to the remote unit T106 through a single feeder T105. The end unit T106 restores one signal to the original two signals and completes MIMO signal coverage through the antenna.

Embodiment example 2

[0032] Implementation case 2: When one near-end unit has multiple remote units, it is necessary to add a power distribution device (such as a power splitter) after the near-end unit, and then connect a remote unit through a single feeder. The near-end unit is placed on the side close to the signal source, and the remote unit is placed at each coverage point. see figure 2 As shown in the following example, the MIMO base station T201 combines the two signals coupled by the couplers T202 and T203 into one signal through the near-end unit T204, and then distributes appropriate power through the power splitter T205, using a single The feeder T206 is transmitted to the remote unit T207, and the remote unit T7 restores one signal to the original two signals and completes MIMO signal coverage through the antenna.

Abstract

The invention relates to a system for realizing mobile communication multiple input multiple output (MIMO) indoor coverage by a single feeder, which consists of near-end units and remote-end units, wherein one near-end unit can be matched with a plurality of remote-end units, and the near-end units and the remote-end units are connected through the single feeder. The system uses one single feeder for transmitting MIMO signals, the problem of coverage occasion of installation limitation of a plurality of feeders in a MIMO system can be solved, and a new system solution is provided for the MIMO indoor coverage.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a system for realizing mobile communication MIMO (Multiple Input Multiple Output) indoor coverage by using a single feeder. Background technique [0002] With the rapid increase in demand for data communication services, mobile communication services have transitioned from voice services to voice, data, and image integrated services. In order to meet the needs of broadband data communications, the construction of wireless broadband access networks has become the focus of future mobile network construction. In the construction of 2G, 3G, and WLAN networks, the indoor distribution system other than the base station equipment plays an important role because of its flexible use, quick layout, and low cost. It provides high-quality services for indoor high-end users, and also reduces indoor coverage. Network costs, avoiding the phenomenon of too many cells in the indoor d...
