Parameter estimation of multi-transient signal using band-pass matrix pencil method

In this paper an application of band-pass matrix pencil (BPMP) method for accurate estimation of controlling parameters (amplitude, frequency, phase and damping factor) of the multi-transient signal has been shown. In case of low signal-to-noise ratio (SNR), matrix pencil (MP) method fails to estimate the values of parameters of the considered signal whereas BPMP method is robust one. So, BPMP method is applied for estimation of the multi-transient signal in case of the worst signal condition. In BPMP method the signal-to-noise ratio (SNR) can be improved by utilizing the mechanism of pre-filtering using IIR filter. Pre-filtering is not a trivial one, so backward process for the IIR filter is applied. To validate the proposed method, the multi-transient signal is taken as a test signal for simulation purpose and the obtained parameters are compared with the true values.
