"The main goal of this book is to define and study the Fourier transform of stochastic processes. ... the author provides a modern unity of Fourier analysis and stochastic processes, presented together in a unique way. The ideal audience would be someone with exposure to analysis and probability at the graduate level who is interested in applications of Fourier analysis to stochastic processes. ... this unique analytic treatment of stochastic processes provides a nice addition to the literature." (Steven Michael Heilman, Mathematical Reviews, June, 2015) "This is clearly an academic text, very well written and organized, with a high pedagogical quality ... . This is a very interesting book adequate to support Master or PhD courses in Stochastic Processes. ... it is accessible to larger audiences and useful for professionals working, for instance, in electrical engineering and communications, biology, economics and finance, but not only." (Manuel Alberto M. Ferreira, Journal of Mathematics and Technology, Vol. 6 (1), 2015) "This is a nice and modern book on the Fourier theory of functions, finite measures and stochastic processes with a lot of examples and exercises. ... it may also be accessible to a large audience (electrical engineers, biologists and economists), since the author made the text as self contained as possible and provided a lot of examples in each chapter relevant from the point of view of applications. I warmly recommend the book for graduate students and researchers as well." (Matyas Barczy, Acta Scientiarum Mathematicarum, Vol. 81 (3-4), 2015)
