This textbook focuses on the fundamental principles and the essential and latest technologies required for the successful design of modern wireless communications systems. The authors provide detailed coverage of the lower layers of the open systems interconnection model of the International Organization for Standardization, particularly the physical and medium-access control layers.

Wireless Communication Systems (second edition) is thoroughly reorganized for easy understanding and contains much new information, reflecting recent changes in this fast-moving field. The major enabling technologies supporting 5G and 6G cellular communications and wireless networking systems receive attention and technical and practical approaches are emphasized over exhaustive mathematics. Features of the second edition include:

• more extensive and detailed coverage of cooperative communications and network coding;
• dedicated chapters on elements of networking and the Internet of Things;
• new content on network security;
• condensation of information about peripheral technologies to provide clearer focus on the linchpin issues; and
• substantial revisions in each existing chapter.

The material covered in this textbook is sufficient for a two-semester course at the advanced undergraduate or beginning graduate level.
