Preface

Radio propagation measurements and channel modelling continue to be of fundamental importance to radio system design. As new technology enables dynamic spectrum access and higher data rates, radio propagation effects such as shadowing, the presence of multipath and frequency dispersion are the limiting factors in the design of wireless communication systems. While there are several books covering the topic of radio propagation in various frequency bands, there appears to be no books on radio propagation measurements, which this book addresses at length. To provide the reader with a comprehensive and self-contained book, some background material is provided in the first two chapters, which cover the fundamentals of radio transmission including propagation in ionized media. The aim here is to bring two different communities together, namely those working on communication via the ionosphere in the high frequency (HF) band with those working at ultra-high frequency (UHF) through examples that illustrate that although the medium of transmission is different the principles are similar. Thus the two-ray model commonly used in mobile radio propagation studies is shown to be applicable to the two magneto-ionic waves that propagate via the ionosphere. The distortion effects on wideband signals as they travel through a frequency dispersive medium is studied for both narrow pulses and for frequency modulated continuous wave signals to illustrate the principles of transmission. Some ...
