Matched filters for system identification
ANCA TOMESCU, F. M. G. Tomescu · IEEE Transactions on Automatic Control · 1970
In this correspondence a new method is described for determining the impulse-response of an approximately linear system using the cross-correlation function between an input pseudorandom binary signal and the corresponding output signal of the system under study. A filter matched to a periodic pseudo-random binary signal is used to obtain the needed correlation function.
