Enhanced Radio Access Technologies for Next Generation Mobile Communication presents a comphrenhensive overview of the latest technology developments in the field Mobile Communications. This monograph focuses on the fundamentals of mobile communications technology and systems, including the history and service evolution of mobile communications and environments. Further to this, CDMA technology including spread spectrum, orthogonal and PN codes are introduced. Other important aspects include fundamentals of single carrier CDMA technologies, DS CDMA, Broadband CDMA with frequency domain equalizer, and multi-carrier CDMA technology for high speed data transmission including MC-DS/CDMA, MC-CDMA. Finally aspects of modern cellular systems such as cdma2000/1xEv-Do/1xEv-Dv and WCDMA/HSDPA are introduced and existing and developing wireless data services, such as Wi-Fi, Bluetooth, UWB, WiBro/Mobile WiMAX, and digital broadcasting services like DVB, DMB, ISDBT are described.

This three-volume set LNICST 701-703 constitutes the refereed post-conference proceedings of the 15th EAI International Conference on Wireless and Satellite Systems, WiSATS 2025, held in Harbin, China during August 7–9, 2025.The 108 full papers presented in these volumes were carefully reviewed and selected from 274 submissions.They are organized into the following topical sections:Part I: Al-Enabled Communication and Sensing Systems; Signal Processing and Intelligent Networking in Challenging Environments; and Intelligent Communication, Networking, and Edge Computing Systems.Part II: Intelligent Communication, Networking, and Edge Computing Systems; Multi-Modal Perception and Intelligent Signal Analysis; Waveform Design, Electromagnetic Structures, and Signal Processing; and Interference-Aware and Secure Communication Techniques for Future Networks.Part III: Interference-Aware and Secure Communication Techniques for Future Networks; Array, Design, and Decision-Making in Complex Systems; and Learning-Based Signal Recognition, Estimation, and Perception.
