  • This book is the result of close cooperation between industry and academia, notably Ericsson and two universities in Sweden: Chalmers University of Technology (CTH) in Göteborg and The Royal Institute of Technology (KTH) in Stockholm. In 1987, a student at CTH presented her PhD thesis on the topic of conformal antennas. It was then considered an interesting but difficult technology with no immediate application.

  • Adaptive beamforming wasinitially developed in the 1960s for the military applications of sonar andradar, in order to remove unwanted noise and jamming from output. The related the literature of the past 40 years is extremely rich [201-2371 and since this book is mainly concerned with the networking aspects of wireless systems, rather than with specific antenna array designs, here we will restrict our discussionson the topic to a rudimentaryoverview.

  • Estimating the directions of arrival (DOAs) of propagating planewaves is a requirement ina variety of applications including radar, mobile communications, sonar, and seismology. Due to its simplicity and high-resolution capability, ESPRIT (Estimation of Signal Parameters via Rotational Invariance Techniques) [18] has become one of the most popular signal subspace-basedDOAor spatial frequency estimation schemes. ESPRIT is explicitly premised on a point source model for the sources and is restricted to use with array geometries that exhibit so-called invariances [18]....
