Intended to show how to attain reliable digital communications and coding, this book covers subjects such as Fourier theory, digital signaling methods, probability theory, and noisy channels. Moreover, it goes beyond standard treatments to cover emerging topics that will soon becomecommonplace in this rapidly changing field. Throughout, the topics selected are those in which the mathematics is both conceptually straightforward and useful in other contexts. Carefully worked out exercises at the end of each chapter illustrate the material presented and subsidiary themes.Advanced students and academics in communications in the field of electrical engineering will appreciate the unusually rigorous and realistic approach to the subject. Students and academics in physics, computer science, and mathematics concerned with communications will also find the book ofinterest.
