Features

  • Provides a comprehensive survey of the theory, fundamentals, and applications of smart antennas
  • Discusses the various structures suitable for the narrowband and broadband fields
  • Presents an analysis of adaptive processing
  • Describes DOA estimation methods, as well as performance comparisons and sensitivity analyses
  • Reviews fading channels, the distribution of signal amplitude and received power, and noise- and interference-limited single-antenna systems in Rayleigh and Nakagami fading channels.
  • Explores diversity combining schemes including selection combiner, switched diversity combiner, equal gain combiner, maximum ratio combiner, optimal combiner, and more
  • Analyzes systems in various fading conditions by deriving results for average bit error rate and outage probability
  • Summary

    The use of smart antennas to increase mobile communications channels has re-ignited research and development in the field. Practicing engineers are eager to discover more about this subject, and need a comprehensive book that can provide a learning platform and prevent the loss of time spent on searches through journal literature.

    Smart Antennas examines nearly all aspects of array signal processing and presents them in a logical manner. It delivers a detailed treatment of antenna array processing schemes, adaptive algorithms to adjust weighting, direction of arrival (DOA) estimation methods, diversity-combining methods that combat fading and reduce errors.

    The book introduces the various processor structures suitable for the narrowband field, examining the behavior of both element space and beamspace processors. It then explores adaptive processing, focusing on the simple matrix inversion algorithm, constrained least mean squares (LMS), the neural network approach, and more. The text also describes smart antennas that are suitable for broadband signals, and presents analyses and techniques suitable for correlated fields in narrowband and broadband signals.

    This volume supplements its content with extensive references, enabling you to further investigate smart antenna array schemes and application.
