|Title||SYSTEM IDENTIFICATION METHOD|
Quick real-time identification and estimation of a time-non-varying or time- varying system. A new H.infin. evaluation criterion is determined, a fast algorithm for a modified H.infin. filter based on the criterion is developed , and a quick time-varying system identifying method according to the fast H.infin. filtering algorithm is provided. By the fast H.infin. filtering algorithm, a time-varying system sharply varying can be traced with an amoun t of calculation O(N) per unit time step. The algorithm completely agrees with a fast Kalman filtering algorithm at the extreme of the upper limit value. If the estimate of impulse response is determined, a pseudo-echo is sequentiall y determined from the estimate and subtracted from the real echo to cancel the echo. Thus an echo chancellor is realized.
