Present-day mobile communications systems can be classified as fixed-to-mobile because they allow mobility on only one end. In answer to the consumer demand for better coverage and quality of service, emerging mobile-to-mobile (M-to-M) communications systems allow mobile users or vehicles to directly communicate with each other. This practical book provides you with a detailed introduction to state-of-the-art M-to-M wireless propagation. Moreover, you get expert guidance on rapid implementation of these communications systems. The book offers you a thorough understanding of signal propagation and channel models for vehicle-to-vehicle, air-to-ground, and underwater vehicle-to-underwater vehicle communications. This authoritative resource is packed with over 1000 equations and more than 100 illustrations. DVD Included! Contains time-saving MATLAB code for the models discussed in the book, providing valuable tools that you can use for your projects in the field.
