Written by the developers of the new 21st century HF (high frequency) radio technology, this groundbreaking resource presents the powerful new capabilities and technical details of 3G and WBHF (wideband high frequency) waveforms to help professionals understand and use the ionospheric channel for video and high-speed data transmission.
Featuring more than 180 illustrations, this practical book enables engineers to utilize this technology to communicate voice and data over the horizon without needing anyone else's infrastructure, send video beyond line of sight from moving platforms, and communicate over long ranges at such low power that it is nearly undetectable. Readers learn the rationale behind the new US and NATO standards for HF radio communications directly from their developers. Additionally, the book looks at the future direction of this technology area and the open problems requiring further research.

Are you an HF system architect and engineer? If you are, then this book is for you. Authors Eric E. Johnson, Eric Koski, William N. Furman, Mark Jorgenson and John Nieto, have done an outstanding job of writing a book about technology—a celebration of innovation in HF radio at the dawn of the twenty-first century. Authors Johnson, Koski, Furman. Jorgenson and Nieto, begin with an historical perspective and an introduction to HF radio. Next, the authors describe the challenging ionospheric channel that is used for communicating beyond the line-of-sight. In addition, they then discuss the state-of-the-art serial-tone modem waveforms and protocols. The authors also summarize the second-generation ALE system, so that there is a baseline for comparison with 3G ALE. Then, they continue with a thorough discussion of 3G technologies, an integrated suite that includes ALE, data transfer, traffic management, and automatic link maintenance protocols. The authors then describe wideband HF data waveforms, and how they communicate in real-time, and in full-motion video over thousands of miles via HF skywave channels. Finally, they conclude by looking ahead to the possible next steps in the advancement of HF radio technology, including the possible application of cognitive radio techniques to the problem of finding usable portions of wideband HF channels in the presence of dynamic interference. This most excellent book describes HF radio technology, and offers ideas for applying it, and evaluating the performance of 3G and wideband HF systems using both simulation and real-world measurements. More importantly though, technical details are included throughout this great book, but they may be skipped by readers who are interested in applying the new technologies to practical problems rather than in designing equipment.
