An updated reference for radio interference modelling and spectrum management

Now in its Second Edition, Interference Analysis provides a thorough treatment of interference methods from regulatory motivations through to sophisticated modelling algorithms. This edition, which incorporates results from WRC-19 and WRC-23, covers modern radio communication systems from 5G deployments to satellite mega-constellations such as Starlink. It addresses radio system technologies such as phased arrays, power control algorithms, adaptive coding and modulation (ACM), including derivation of spectrum efficiency and throughput.

Interference Analysis adds new sections on satellite issues, including sun-synchronous orbits, geometry for missions to the Moon and Mars, ITU-R regulatory processes, non-GSO satellite coordination methods, derivation of equivalent power flux density (EPFD) limits, Resolution 770 methodology, Resolution 609 analysis, Direct to Device (D2D) systems and satellite system design.

Readers will also find:

• Detailed treatment of national and international regulatory regimes governing spectrum licensing, frequency assignment, and coordination procedures
• Link engineering from basic concepts such as decibels, carrier types, access methods, noise, filters, and antennas all the way to link budgets, including methods for their design and how to include margin for interference
• Descriptions of the propagation models that could be used for a wide range of service types including terrestrial (point-to-point and point-to-multi-point), ground-to-air and Earth-to-space paths
• Algorithms, methodologies, and techniques for radio interference simulation applicable to system design, coordination studies, and regulatory analysis.

Designed for engineers developing, providing, or operating satellite or terrestrial radio-communication systems, this reference also serves PhD and MSc students in radio communications and planners and managers at companies operating such systems. It supports technical studies for system design, frequency assignment, coordination, and regulatory analysis.
