Probability and Random Processes: With Applications to Signal Processing and Communications
Probability and Random Processes, Second Edition presents pertinent applications to signal processing and communications, two areas of key interest to students and professionals in today's booming communications industry. The book includes unique chapters on narrowband random processes and simulation techniques. It also describes applications in digital communications, information theory, coding theory, image processing, speech analysis, synthesis and recognition, and others.
Exceptional exposition and numerous worked out problems make this book extremely readable and accessible. The authors connect the applications discussed in class to the textbook. The new edition contains more real world signal processing and communications applications. It introduces the reader to the basics of probability theory and explores topics ranging from random variables, distributions and density functions to operations on a single random variable. There are also discussions on pairs of random variables; multiple random variables; random sequences and series; random processes in linear systems; Markov processes; and power spectral density.
This book is intended for practicing engineers and students in graduate-level courses in the topic.

How It Compares
More application-oriented than Papoulis & Pillai's classic text and broader in scope than Kay's estimation-focused volumes — it balances theory, worked examples, and simulation for DSP/communications engineers.
