Distortion Analysis on Measuring the Impulse Response of a System Using a Crosscorrelation Method
Nevio Benvenuto · AT&T Bell Laboratories Technical Journal · 1984
In this paper we analyze the characteristics of a crosscorrelation method for measuring the impulse response of an unknown system. This analysis may also be of some interest in the area of synchronization of pseudonoise systems. In the first part of the paper a closed-form expression for the main component of the probing pulse is derived. This result may be used to quickly estimate the effect of various system parameters on the measurement's accuracy. In the second part results are presented for two system configurations.
