Radio Propagation and Adaptive Antennas for Wireless Communication Links
Terrestrial, Atmospheric and Ionospheric
Chapter One
Fundamentals of Radio
Communications
The purpose of this chapter is to familiarize the reader with the basic propagation
characteristics that describe various wireless communication channels, such as
terrestrial, atmospheric, and ionospheric for VHF to the X-band. Well-known
standards in wireless communication are introduced for the prediction of path
losses and fading effects of any radio signal in various communication links, and
finally, new possibilities that can be obtained using smart antennas are discussed.
1.1. RADIO COMMUNICATION LINK
Different radio communication links (land, land-to-air, air-to-air) covering different
atmospheric and ionospheric conditions, include several components having a
plethora of physical principles and processes, with their own independent or
correlated working characteristics and operating elements. A simple scheme of such
a radio communication link consists of a tr ... read full excerpt from Radio Propagation and Adaptive Antennas for Wireless Communication Links: Terrestrial, Atmospheric and Ionospheric ebook
