Abstract

This invention relates to a method for testing intelligent antenna faults including: setting the TR switches of all antenna channels a receiving mode and that of the correcting channel a transmission mode, in which, the correcting antenna sends down-line signals to judge if the coupled network and feed lines connecting the array elements are normal by the tested emission signal power of the correcting antenna and the receiving signal power of the array element of the antennas, then to detect if the antenna element of the normal test state is disabled, which judges if the power defference of the measured receiving signal and emission signal is less than a throshld value designed by a fixed coupled relation to get the test result of the fault of intelligent antennas.

Description

technical field [0001] The invention relates to a fault detection method for a smart antenna by a base station adopting smart antenna technology in the communication field. Background technique [0002] The existing smart antenna technology is a new technology that is getting more and more attention in the field of mobile communication. Especially in the TDD working mode, the uplink and downlink channels use the same carrier frequency, so it can be considered that the uplink and downlink channels of the same user are completely symmetrical. , which is conducive to the use of smart antenna technology. [0003] The smart antenna can adaptively adjust the direction of the beam according to the change of the user's position, so that the received power of the desired user is maximized, and at the same time, the interference of the undesired user is reduced, so as to achieve the purpose of improving the system capacity. However, when one or several elements of the smart antenna f...
