Effect of Wideband Signals on Smart Antenna

Mr. Balaji G.Hogade1, Dr Shrikant K Bodhe

Over the last few years, wireless cellular communications has experienced rapid growth in the demand for provision of high data rate wireless multimedia services. For a fixed bandwidth of spectrum there is a fundamental limit on the number of radio channels that are realized by wireless communication systems. Anticipating such limits, considerable amount of work has to be done on the use of time, frequency, and coding techniques to increase the capacity. This motivates the need to find ways to improve the spectrum efficiency of wireless communication systems. Smart antennas have emerged as a promising technology to enhance the spectrum efficiency of present and future wireless communications systems by exploiting the spatial domain. The aim of this paper is to investigate smart antenna applications for Direct Sequence Code Division Multiple Access (DS-CDMA) systems and to study the effect of wideband signals on smart antenna.
