Base station test method and equipment

Abstract

The invention discloses a base station test method and equipment. The method comprises the following steps that: phases between a radio frequency unit and an intelligent antenna coupling disc are calibrated, so that consistency of phase differences of all channels is realized; in covering ranges of antennas of the base station, calculation phase difference values of from reception positions at angles needing to carry out testing to all antennas are determined; when a signal source sends signals and a frequency spectrograph receives signals, the calculation phase difference values at all the angle are compensated to phases of all reception channels and all sending channels of the base station and then signal powers on the frequency spectrograph are obtained when the signal source sends signals at the angles; powers that are obtained according to the angles and the signal powers at the angles are used as downlink signal forming results. According to the invention, an external interference signal, an environmental reflection signal and an environmental refraction signal can be avoided; and measurement precision is high and different corresponding relations between measurement positions and signal powers are accurate.

Description

technical field [0001] The invention relates to communication equipment, in particular to a base station testing method and equipment. Background technique [0002] Smart antenna technology is one of the advantages of TD (Time Division) mode communication systems. Smart antennas can increase the gain of received signals, improve the gain of downlink signals through shaping algorithms, and reduce mutual interference between users. [0003] Existing technologies for testing smart antennas mainly include: [0004] 1) Use a channel simulator to set different delays (or phase differences) on each radio frequency channel; [0005] 2) Two radio frequency units are used for docking, one for receiving and the other for sending, and the phase of each signal is changed at the sending end; [0006] 3) Use the terminal to conduct business tests in the antenna coverage area; [0007] The disadvantage of the existing measurement method 1) is that the test device is complicated and the c...
