Abstract

The widespread use of multi-channel systems and signal processing methods is the development trend of modern radio engineering information systems. The case examples are multi-channel filtering and spectral analysis devices, which are discussed in detail in this monograph. Exceptional opportunities for improving methods and devices for information processing emerge from the use of information and, in particular, structural redundancy that appears as a result of the multi-channel processing of radio signals with a high-frequency resolution. This has resulted prominently in recent years. Solving the problems of study, design, and implementation of spectral analysis tools on acoustic waves are the most important tasks of applying the latest achievements in the development of technologies, methods, algorithms, structures, and devices for radio signals spectral processing in modern multifunctional multichannel radio information systems.
