Spectral Representation of WSS Processes,. We want to obtain a generalisation of the expression of purely harmonic processes . in the case of WSS processes that would be of the form ., where the nature of . should be specified. This representation will enable the filtering of stationary processes to be studied in a simple way in the next chapter.

Filtering of WSS Processes,. We wish to generalise the results obtained in the context of deterministic signal filtering in the case of WSS process filtering.

Linear Prediction of WSS Processes,. We wish to approach, in the sense of the minimum error variance criterion, the variable .. of a WSS process . (..). by means of a linear combination of the random variables (..).≥1. Some important applications like system modelling, filter synthesis, or signal compression, use the results of linear prediction theory.

Higher Order Statistics,. In this chapter, we present a few basic notions about higher order statistics that generalise notions defined above for second order statistics. We show, in particular, how the definition of the spectral representation of a process can be generalised for processes that are stationary at orders higher than two.

Rational Spectral Densities,models involve few parameters, since in many situations it is sufficient to use rational PSDs of low degree. Finally, the identification or the estimation of the parameters of a rational PSD is relatively simple, as will be seen in the following chapters. We shall therefore indicate here some important results about these processes.
