Requirements (Subjects that are assumed to be known)

Calculus I
Linear Algebra

The aim of this course is to make the student familiar with the basic concepts of probability, random variables and stochastic processes. In order to achieve this goal, the student should acquire knowledge and skills.
With respect to the knowledge, at the end of the course, the student should be able to:
-Know and use the basic concepts and properties of probability.
-Understand the concept of density and probability function of random variables and vectors.
-Identify and understand transformations of random variables and vectors.
-Understand the concept of signals and knoise as stochastic processes.
The student will gain specific and general skills:
Specific skills:
-Calculate the reliability of a system
-Manage the concept of random variables in the context of telecommunications
-Work with transformations of random variables and their properties
-Identify and classify stochastic process, and calculate their statistics.
General skills:
-Capacity to identify and apply theoretical concepts to real problems. This skill will be acquired by solving problems proposed in class
-Hability to analyze data and interpret results. This skill will be developed in class and in computel labs.
-Effective communication of knowledge and statistical results. This skill will be acquired by solving problems in class and in computer labs.
-Capacity to work in groups, in an effective, responsible and creative manner. This skill will be acquired by solving computer labs exercises in groups and solving problems in class.

-Bayes Theorem
*Random Variables
-Definition of random variable
-Dicrete random variables: probability and distribution functions
-Continuous random variables: density and distribution functions
-Moments of a random variable
-Transformation of random variables
*Probability models
-Bernouilli and Binomial
-Poisson
-Exponencial
-Normal
-Central Limit Theorem: Approximation of random variables
*Random Vectors
-Joint distribution
-Discrete and continupus random vectors: Joint probability, density and distribution functions
-Marginal distributions
-Conditional distributions, independence of events
-Moments of a random vector
-Transformations of renaom vectors
*Stochastic Processes
-Definition and classification of processes
-Distribution function
-Characteristic measures: Mean, Variance, Autocovariance, Autocorrelation
-Correlation between processes, independence, orthogonality
-Stationarity
-Ergodicity
