摘要
PURPOSE: A sector antenna system of the CDMA(Code Division Multiple Access) mobile communication system is to provide a sector antenna system to proceed more efficient soft hand-off, by optimizing the cell structure divided into a plurality of sectors. CONSTITUTION: The cell structure divided into three sectors in the CDMA system is composed of four cells(A,B,C,D) and two mobile stations(100,101). Incident angles for each cell are same(alpha1 = alpha2 = alpha3) in a point(102) the boundary lines of three cells meet. But, in other boundary point(103), except for the boundary point(102), incident angles for each cell are all not in accord.
