Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0038] The main idea of ​​the present invention is: after the antenna array is installed, use the test UE to communicate in the sector corresponding to the antenna array, and collect the channel impulse response (CIR, Channel impulse response) of each antenna in the antenna array corresponding to the UE. ), and then calculate the phase difference between the received signals of each pair of adjacent antennas according to the collected CIR, and judge the correctness of the antenna jumper line sequence according to the difference between the phase differences.

[0039] The method provided by the present invention is carried out according to the characteristics of the antenna array, that is: the signals of adjacent antennas have the same phase difference, t...

Abstract

The invention discloses a detection method of the jumper wire sequence of an antenna, comprising the following steps of: previously setting a first threshold value; after an antenna array is completely installed, firstly acquiring the CIR (Channel Impulse Response) of each antenna in the antenna array; then calculating the phase difference between received signals of each pair of adjacent antennae according to the acquired CIR of each antenna; finally judging according to the difference value between the phase differences; if the difference value between any two phase differences is less thanthe first threshold value, judging that the jumper wire sequence of the antenna is accurate; and if not, judging that the jumper wire sequence of the antenna is wrong. The invention can be used for realizing the detection of the accuracy of the jumper wire sequence of the antenna.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for detecting the line sequence of an antenna jumper. Background technique [0002] TD-SCDMA system uses smart antenna technology. There are many jumper wires between the radio frequency remote unit (RRU) and the antenna, which is prone to jumper wire sequence errors, which greatly affects the performance of the smart antenna. In order to reduce the occurrence of such errors, the industry adopts a method of marking the jumpers from the RRU to the antenna with different colors, but this still cannot completely avoid jumper wire sequence errors, such as installation errors. [0003] When the sequence of the jumper line is wrong, it will have a certain impact on the performance of the TD-SCDMA system. Because the jumper line sequence error will affect the correctness of the angle of arrival (DOA) estimation, thereby affecting the performance of other algorith...
