Stochastic Processes

 

Course Description:

 

The course goal is to present random processes at the level of Stochastic Processes by Ross. Courses with similar titles appear in undergraduate curriculum. This course is expected to solidify the basic probability foundation given at the undergraduate level and study the stochastic processes with their applications.  At the end of course, students should have the necessary background for statistical DSP, communications, queuing theory studies.

 

Course Outline:

 

  1. Introduction to Probability
    1. Finite sets, events on real line, events on function spaces etc.
    2. Random variables
    3. Moments, characteristic functions, conditional moments
    4. Sequence of random variables
    5. Correlation matrix,  covariance matrix
    6. Auto-correlation sequence, power spectrum density
    7. Convergence of random sequences
  2. Random Processes
    1. Stationarity
    2. Wide sense stationarity
    3. Ergodicity
    4. Processing of random processes with linear time invariant systems
  3. Important Random Processes
    1. Poisson process
    2. Markov chains (discrete time)
    3. Brownian Motion, level-crossing problems, continuous time Markov chains, martingales (as much as time permits)

 

Textbooks:

1.      Sheldon Ross, Introduction to probability models (8th Edition), Academic Press, 2003  (for the first half of the coursem, other topics are lightly covered)

2.      Sheldon Ross, Stochastic Processes (2nd Edition), John Wiley and Sons, 1996. (for the second half of the course, requires some probability background)

3.      A. Papoulis,  Probability, Random Processes and Stochastic Processes, (3rd edition or later), Mc-Graw Hill, 1991. (not required, but highly recommended)

 

Evaluation: Homework assignments (some of them has Matlab problems), two midterms and a final. Announced quizes are also planned.
