Preface
A constructive approach to Poisson point processes (PPPs) is well suited to those who seek to learn quickly what they are, how they are used, and—above all— whether or not they can help the reader in whatever application they are working on. To help readers reach these goals, PPPs are defined via a two-step realization, or simulation, procedure. This procedure is subsequently used to obtain many wonderful properties of PPPs. The approach is pedagogically efficient because it uses a constructive definition of a PPP in place of the traditional PPP axioms that include, for example, independent scattering. The two approaches are in fact mathematically equivalent. The question of elegance is a matter of taste. Many readers will find the constructive definition easier to understand than an axiomatic one, especially on first encounter. In any event, the simulation approach is taken here because it provides an efficient entrée to PPPs and point processes generally. There are now several books on PPPs and related topics. Most seem to be written by mathematicians striving for mathematical rigor, and these are valuable books for that very reason. Many practitioners, however, do not have the background to read them without a serious commitment of time and effort. What I felt was lacking was a book that made PPPs accessible to many mathematically capable readers and that provided insight and technique without recourse to an axiomatic measure-theoretic approach. Therefore, while I was writing the book, the audience foremost in my mind was graduate students, especially beginning students in electrical engineering, computer science, and mathematics. The real audience for this book is, of course, anyone who wants to read it. PPPs came only slowly to my attention and from many sources, most of
