Wireless Communication Systems

The application of antenna arrays has been suggested in recent years for mobile communication systems to overcome the problem of limited channel bandwidth thereby satisfying an ever growing demand for a large number of high bit rate mobiles on communication channels. It has been shown by many studies that when an array is appropriately used in a mobile communication system it helps in improving the system performance by increasing channel capacity and spectrum efficiency. It also extends the range of coverage reduces multipath fading and co-channel interference. These benefits are achieved by adjusting the antenna radiation pattern for a given wireless environment. This book aims at developing novel analytical and simulation models for assessing the performance of a steered-beam adaptive antenna array with an arbitrary number of variably spaced dipole elements operating with incident narrow-band signals of various bandwidths and powers.
