It has applications in filter design and speech coding.[a,g]=lpc(x,p) finds the coefficients of a pth-order linear predictor (FIR filter) that predicts the current value of the real-valued time series See our User Agreement and Privacy Policy. Predictions such as x ^ ( n ) {\displaystyle {\widehat {x}}(n)} are routinely used within Kalman filters and smoothers [1] to estimate current and past signal values, respectively. Another way of identifying model parameters is to iteratively calculate state estimates using Kalman filters and obtaining maximum likelihood estimates within Expectation–maximization algorithms.
