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. In system analysis, a subfield … Se mer The most common representation is $${\displaystyle {\widehat {x}}(n)=\sum _{i=1}^{p}a_{i}x(n-i)\,}$$ where $${\displaystyle {\widehat {x}}(n)}$$ is the predicted signal value, $${\displaystyle x(n-i)}$$ the … Se mer • PLP and RASTA (and MFCC, and inversion) in Matlab Se mer • Autoregressive model • Linear predictive analysis • Minimum mean square error Se mer • Hayes, M.
