This book was released on 1989 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today's communications and detection systems feature sophisticated signal processing techniques, and advanced theories can now be applied in order to improve system efficiency. These theories are used to achieve more accurate channel characterisation and to produce more complex and more powerful system methods, which are tending now away from analog processing towards digital systems. New methods, such as digital signal processing, matching methods, spread spectrum and encoding are leading to the use of an increasing number of frequency bands in order to improve the security and speed of communications and to enhance location accuracy in radar and radiolocation systems. The signal processing operations required in order to use such systems can now be carried out by dedicated high-speed components, signal processors and programmable systems, from microprocessors to computers, and this has modified equipment design and the technical approaches adopted. The final aim of these techniques is to achieve optimum matching of systems to the propagation environment, which imposes its own characteristics. In military communications or detection systems, this matching is vital, given in particular the constraints imposed by the environment and the operational requirements. Keywords: NATO furnished, Broadband transmission channels.
