Topic 71: Introduction to System Response to Random Signals (PETARS, Chapter 10)

This Topic introduces the concept of calculating the stochastic process at the output of a known deterministic system, given a stochastic process at the input of the system. This concept is…

Topic 70: Cross-Power and Complex Spectral Densities (PETARS, Chapter 9)

This Topic extends the definition of the power-spectral density in two ways. First, it considers the cross-power spectral density (CPSD) for considering the spectral characteristics of two-jointly…

Topic 59: Introduction to Stochastic Processes (PETARS, Chapter 8)

In this first video of the Statistical Signal Processing part of the PETARS course, the notion of random signals, or stochastic processes is introduced. It is defined as a natural extension to the…

Topic 50: Linear Least Squares Estimation (PETARS, Chapter 6)

The special case of linear least squares is presented as an extremely useful estimation approach, in cases when the signal model can be written as a linear combination of known basis functions, with…

Topic 49: Least Squares Estimation (PETARS, Chapter 6)

The least squares approach is presented as a non-probabilistic method for designing an estimator of a set of parameters, assuming a model is provided for describing the data. This is presented as…

Topic 44: Minimum Mean Square Error Estimators (PETARS, Chapter 6)

This video introduces the simple mean square error (MSE) as a criterion which trades-off bias and variance for an estimator. The relationship between the MSE and bias and variance is defined. The…
