Abstract :
Advanced antenna arrays at the base stations are one of the key techniques to reduce interference in WCDMA cellular systems. This paper presents the use of the beam steering method with circular arrays along with Chebyshev current distributions in order to reduce the value of the ratio of intercell interference to received intracell power in WCDMA cellular systems. The intercell to intracell interference ratio of the beam steering case with the proposed arrays is compared to that of the conventional omnidirectional case. The obtained results demonstrate a notable superiority of the proposed antenna arrays.
