Analysis of circular arrays as smart antennas for cellular networks

Abstract

Smart antennas are considered vital components of the future 3G mobile communication networks based on www.symena.com, G.V. Tsoulos et al. (2000), and P. Gendren (2002). The topic is very broad in nature and includes adaptation algorithms according to Y.S. Song et al. (2001) and C. Paleologu et al. (2002), receiver architecture, channel modeling and estimation, adaptive coding, antenna theory by H.S. Cho et al. (2001), A. Sabharwal et al. (2000) and M.L. Leou et al. (2000) etc. This paper is a study of circular array applications as smart antennas intended to evaluate the advantages and the drawbacks and to establish guidelines to design its parameters. A classification of smart antennas is also included.
