Embodiment Construction
[0042] Specific embodiments of the present invention will be described in more detail below in conjunction with the accompanying drawings.
[0043] Referring to accompanying drawings 1 and 2, they are schematic diagrams of arrangement modes of outdoor unit antenna arrays of smart antennas: circular array and linear array respectively.
[0044] The method for detecting the connection sequence of the radio frequency coaxial cable between the smart antenna array and the outdoor radio frequency front-end unit according to the present invention respectively processes the data after collecting the uplink channel at the base station end and performs smooth correlation, and constructs user antenna weight coefficient traversal Matrix, beam space search for the maximum value of the corresponding arrangement, detection of the maximum value corresponding to the angle to eliminate special angle set data, search for the maximum power of all arrangements to obtain the precise arrangement posi...
