Spectrum monitoring evolution
In this issue
The goal of spectrum management is to maximize spectrum efficiency, minimize interference and eliminate unauthorized and improper use of the spectrum. As the eyes and ears of the spectrum management process, spectrum monitoring is very necessary and important in the management of spectrum resources, radio stations of various types, and the electromagnetic environment by providing valuable monitoring data, including spectrum occupancy and characteristics of signals, such as field strength, bandwidth, modulation type, locations of emitters, etc.
Radiocommunication systems are in a constant and rapid evolution. Future spectrum monitoring systems should therefore thave the capability for monitoring new radiocommunication technologies and systems, such as detection of weak signals, co-frequency signal separation and multi-mode location based on digital signal processing (DSP), RF sensor networking, and other technologies.
