14. Conclusions

Chapter 14 concludes the monograph and proposes specific research problems to be solved by taking the advantages of fractional-order signal processing techniques. The monograph presents fractional processes and fractional-order signal processing techniques from the perspective of fractional signals and fractional-order systems. Fractional processes, which can be considered as outputs of the fractional-order systems, are categorized as constant-order fractional processes, variable-order fractional processes and distributed-order fractional processes. In order to best understand the fractional-order systems and extract valuable information from the fractional-order signals, fractional-order signal processing techniques are put forward for different kinds of fractional signals. Fractional-order signal processing techniques have been extensively used in econometrics, communication, biomedicine, hydrology, linguistics, and so on. we hope that the readers will use fractional thinking to understand natural or man-made phenomena, and use fractional techniques to solve the problems and gain additional insights after reading the monograph.
