Probability, Random Processes, and Ergodic Properties

Robert M. Gray

An authorized free corrected first edition developing probability and random processes toward stationary processes and ergodic reasoning.

Prerequisites

Real analysis, probability and comfort with rigorous proofs. Review measurable sets, integration and convergence of random variables; engineering intuition helps interpret the mathematical models but does not replace it.

Who this book is for

For graduate students and mathematically prepared readers studying stochastic processes in information theory, communication or related areas. The book is useful when a calculation based on averages needs precise assumptions about a process and its long-run behaviour. It provides a demanding theoretical continuation beyond elementary probability or a simulation-led introduction.

Prerequisites

Real analysis, probability and comfort with rigorous proofs. Review measurable sets, integration and convergence of random variables; engineering intuition helps interpret the mathematical models but does not replace it.

What it covers

Probability foundations support the development of random processes, stationarity and ergodic properties. The framework relates mathematical structure to signal models and clarifies the conditions under which time-based observations support a statistical conclusion. Proofs and definitions form the core of the learning rather than a catalogue of process formulas.

How to use it

Keep a list of the modes of convergence and check which one a result actually uses. Test definitions on a simple independent sequence and on a stationary dependent example. Before invoking an ergodic statement, identify the process, transformation and integrability assumption. Compare an ensemble expectation with a time average and explain what additional property is needed to connect them.
