Abstract

In order to reduce the time-domain simulation time of reverberation chamber (RC), this paper investigates the means to predict time-domain responses of RC. A new kind of matrix pencil method (MPM) is proposed based on the modified MPM. Using the proposed method, a fitting formula for the former part of time-domain responses can be determined, which could be used to predict the later part. When the pencil ratio parameter is 0.62, acceptable results can be obtained using the first 20 000 original records to predict the following 20 000 responses. The relative error between the original and the semi-original semi-predicted signals in frequency domain can be guaranteed below 15%. In this way, the simulation time could be saved about 50% compared to the ordinary
