What is a prediction filter?

Predictive filters are a family of estimation techniques. They combine the uncertain prediction from the system's dynamics and the corrupted observation. There are many different predictive filters, each dealing with different types of mathematical represen- tations for random variables and system dynamics.

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 LPC analysis?

LPC (linear predictive coefficients) analysis is a technique for estimating the vocal tract transfer function, from which its poles, he formant frequencies, can be analytically calculated.

What is LPC in wireless communication?

Linear predictive coding (LPC) is a method used mostly in audio signal processing and speech processing for representing the spectral envelope of a digital signal of speech in compressed form, using the information of a linear predictive model.
