The book is devoted to advanced radiocommunication, discussing the merits and operational aspects of spread spectrum signalling. Spread spectrum modulation is emerging as one of the most important tools for combatting a wide range of problems usually encountered in radiocommunication. For military applications the signalling is able to resist difficulties deliberately introduced by an enemy, such as jamming and eavesdropping. For civil application, the efficient signal multiplexing and multipath rejection capability is of great interest. The price paid however is the need for very complex processing of the radio signals. This task put great challenges on new technologies and design, and it is only recently that operational systems have started to emerge from the laboratories.

Mobile communication is one of the most important applications in the tele-communications and IT field. Developments in technology are enabling the design of advanced mobile radio networks linking information processing and data routing, with the radio segment sandwiched between layers of digital signal processors. Spread spectrum technology adapts radio communication to computational data information processing networks.
