What is linear prediction method?

Linear prediction is a mathematical operation where future values of a discrete-time signal are estimated as a linear function of previous samples. In digital signal processing, linear prediction is often called linear predictive coding (LPC) and can thus be viewed as a subset of filter theory.

What is forward linear prediction?

A forward linear predictor is a filter that attempts to predict the u(n) sample from the previous m samples. Forward predictors are causal, which means they only act on previous results.
