Embodiment Construction
[0028] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] figure 1 It is a structural schematic diagram of the smart antenna field test system in the embodiment of the present invention. Such as figure 1 As shown, the smart antenna field test system may include a recording module 1 , a test point selection module 2 , a pattern simulation module 3 , an field field test module 4 and a curve fitting module 5 , and may also include a pre-check module 6 .
[0030] The recording module is used to record the normal direction and downtilt angle of the smart antenna to be tested in the area to be tested when the parameter configuration of the smart antenna to be tested in the area to be tested is normal and the wireless environment meets the preset conditions
[0031] The test point selection module is used according to the normal direction and downtilt angle of the smart antenna to be tested Sel...

The invention discloses an intelligent antenna outfield test method and a system thereof. The method mainly comprises the test point selection and direction pattern fitting of an intelligent antenna outfield direction pattern performance test, specifically, the space correlation of a radio signal and the direction pattern characteristic in a normal shaping condition are employed, some characteristic positions are selected to test, a characteristic point which can not arrive or other test points is completed through interpolating and fitting, and under the premise of ensuring the total quality of an outfield test, the workload of the outfield test is reduced. The technical scheme of the invention is simple and practical, the test holding period in a direction pattern test process can be shortened, the requirement to a testing point is low, the performance test of an intelligent antenna in a network with low cost is facilitated, and the promotion is easy.
Description
technical field [0001] The invention relates to the technical field of communication and wireless network optimization, in particular to a smart antenna field test method and system. Background technique [0002] With the development of wireless communication, more and more wireless systems (such as TD-SCDMA, TD-LTE, IEEE 802.11n and Wimax, etc.) introduce smart antenna technology to improve system capacity, coverage and system throughput. Not only that, mobile terminals have also begun to use smart antennas to improve link quality and user throughput. [0003] The smart antenna estimates the direction of the uplink user (that is, the angle of arrival, DOA—Direction of Angle) according to the uplink signal received by each array element in the antenna array. When transmitting downlink power, set the transmission on each antenna element of the smart antenna according to the estimated direction. Power weights to form beams directed to estimated users. The received power of t...
