Michaelmas term. 16 lectures.

Aims

The aims of the course are to:

  • Study more advanced probability theory, leading into random process theory.
  • Study random process theory and focus on discrete time methods.
  • Introduce inferential methodology, including maximum likelihood and Bayesian procedures, and examples drawn from signal processing. Objectives

Objectives

As specific objectives, by the end of the course students should be able to:

  • By the end of the course students should be familiar with the fundamental concepts of statistical signal processing, including random processes, probability, estimation and inference.

Content

Lectures 1-8: Advanced Probability and Random Processes

  • Probability and random variables

    • Sample space, events, probability measure, axioms.

    • Conditional probability, probability chain rule, independence, Bayes rule.

    • Random variables (discrete and continuous), probability mass function (pmf), probability density function (pdf), cumulative distribution function, transformation of random variables.

    • Bivariate: conditional pmf, conditional pdf, expectation, conditional expectation.

    • Multivariates: marginals, Gaussian (properties), characteristic function, change of variables (Jacobian.)

  • Random processes

    • Definition of a random process, finite order densities.

    • Markov chains.

    • Auto-correlation functions.

    • Stationarity–strict sense, wide sense. Examples: iid process, random-phase sinusoid.

    • Ergodicity, Central limit theorem.

    • Spectral density.

    • Response of linear systems to stochastic inputs – time and frequency domain.

    • Time series models: AR, MA, ARMA

Lectures 9-16: Detection, Estimation and Inference

  • Basic linear estimation theory: BLUE, MMSE, bias, variance

  • Wiener filters

  • Matched filters

  • Least squares, maximum likelihood, Bayesian inference.

  • The ML/Bayesian linear Gaussian model

  • Maximum likelihood and Bayesian estimation

  • Example inference models: frequency estimation, AR model, Estimation of parameters for discrete Markov chain.
