The ideal smart antenna is to align the main lobe of the antenna pattern with the direction of the target user, and the side lobe with the direction of the interference signal. However, the reality is that the direction angle of the main lobe of the antenna is consistent with the direction of the planned cell, but it is limited to a certain extent. physical conditions
If the network coverage is optimized by adjusting the physical parameters of the antenna feeder, it is limited by the adjustable range of the antenna, and the cost of antenna rectification is relatively high, making it difficult to achieve

Embodiment Construction
[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention, and are not used to limit the technical solution of the present invention.
[0025] Whether the current 4G network is a TL common mode or an LTE single mode macro station, most of them can satisfy the waveform adjustment through weights. The smart antennas widely used in the network are multi-arrays. The main function is to arrange and stimulate multiple rows of antennas with the same orientation in a certain way, and to use the principle of wave interference to form an array structure antenna with predetermined beams. The smart antenna can change the directional pattern of the array through the weighted amplitude and phase of the array element signal, that is, control the...

The invention belongs to the technical field of communication, and particularly relates to an antenna weight parameter adjusting method. The method comprises the following steps: according to the number of adjacent cells of which the difference between RSRP of the adjacent cells and RSRP of a main cell is less than a signal strength threshold, the included angle between the azimuth angle of the main cell or the adjacent cells and a test point, and the relationship between the RSRP value of the main cell and set power. The network coverage condition and the signal intensity are judged, so thatthe antenna beam shape is flexibly changed, the signal energy intensity of the main lobe is increased and the sidelobe signal interference is reduced in different coverage scenes by adjusting the antenna weight, and thus the improvement of user perception is realized.
Description
technical field [0001] The invention belongs to the technical field of communications, and in particular relates to an antenna weight parameter adjustment method. Background technique [0002] my country's 4G network has basically achieved full coverage, but in actual construction, it is limited by factors such as LTE capacity, coverage distance, and deep coverage. As a result, in dense urban areas, there are many site constructions, and the wireless environment is relatively complex, resulting in overlapping coverage. , High over-coverage, high quality and poor quality. [0003] The smart antenna widely used at present is multi-array, and the corresponding coverage waveform can be realized by adjusting the amplitude and phase of each array. The LTE smart antenna can change the direction pattern of the array through the weighted amplitude and phase of the array element signal. The antenna weight is the quantitative representation of the specific excitation signal applied to ...
