Özet:

 

The deployment of advanced antenna arrays at the base  stations of cellular systems is a key technique in reducing intercell  interference, and thus increasing the number of served users.  Uniform  circular arrays (UCAs) provide 360 degrees of coverage, their patterns  are steering-invariant and their sidelobe levels are controllable.  This paper investigates the use of UCAs having specially synthesized  patterns at the base stations of WCDMA cellular systems.  The decrease  in the ratio of intercell interference to intracell power resulting  from the use of these arrays in a beam-steering scheme will be  assessed, and the advantages and disadvantages of each pattern type  will be discussed.  The paper also looks into the interference  reduction obtained by stacking several UCAs to form a cylindrical  array.
