<p>The invention relates to a method for improving intelligent antenna array coverage, arbitrary beam forming of the antenna array can be achieved by adjusting n beam forming parameters W(n) based on difference of size and shape parameters between coverage required in engineering design and actually realized coverage. The method includes: setting accuracy of W(n) to be solved, i.e. adjusting step; setting a group of initial values W0(n), a group of square error initial values ε0, counter variable, adjustment termination threshold M and transmission power maximum T(n) of antenna element; the adjustment of W(n) is cyclically performed based on above set values. The antenna radiation parameters can be adjusted by means of gradual approach according to LMS principle, thus actual coverage of antenna array can approach requirement in condition of partial optimum.</p> |
