Embodiment Construction

[0036] 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.

[0037] image 3 It is a flow chart of the base station calibration method provided by the present invention.

[0038] like image 3 As shown, the method includes:

[0039] Step 301, storing phase and / or amplitude compensation data of each calibration channel.

[0040] Step 302, perform phase and / or amplitude compensation on each calibration channel according to the phase and / or amplitude compensation data.

[0041] Step 303, using the compensated calibration path to perform phase and / or amplitude calibration on each transmitting module and / or receiving module.

[0042] Since the phase and / or amplitude characteristics of the calibration path change with the temperature of the calibration network, in order to further improve the accuracy of the phase ...

Abstract

The invention discloses a base station correction method and a correction device. The method comprises the following steps of: storing phase and / or amplitude compensation data of each correction path in advance before phase and / or amplitude correction is performed on each transmission module and / or a receiving module by adopting corresponding correction paths respectively; and performing phase and / or amplitude compensation on each correction path according to the phase and / or amplitude compensation data. The device comprises a storage module and a compensation module, wherein the storage module stores the phase and / or amplitude compensation data of each correction path; and the compensation module is used for performing the phase and / or amplitude compensation on each correction path according to the phase and / or amplitude compensation data in the storage module before the phase and / or amplitude correction is performed on each transmission module and / or each receiving module by adopting the corresponding correction paths respectively. By the method and the device, the base station correction accuracy can be improved, and the process requirements of a correction network are reduced.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a base station calibration method and a calibration device. Background technique [0002] Smart antenna technology is one of the most attractive technologies in mobile communication, and has been applied in TDD mobile communication systems such as TD-SCDMA and TD-LTE. The core of smart antenna technology is downlink service channel shaping. Its main principle is: the terminal sends a reference signal, and the base station receives and demodulates the reference signal to estimate the uplink channel matrix; the base station performs SVD decomposition on the uplink channel matrix to obtain a weighted vector; The uplink and downlink channels are mutually different. The base station uses the weighted vector of the uplink channel matrix to shape the downlink traffic channel; the shaped downlink traffic channel data passes through the transmission path, feeder, an...
