PERFORMANCE OF FREQUENCY DOMAIN METHODS IN THE ANALYSIS OF MULTICOMPONENT TRANSIENTS WHEN THE NOISE IS VERY HIGH

Abdussamad Umar Jibia

Abstract


Transient multiexponential signals occur in different areas of applied science and methods for their analysis continue to
evolve. In addition to time-domain techniques, frequency-domain techniques have been reported. This paper presents
performance comparison of selected frequency-domain techniques when the Signal to Noise Ratio techniques are Minimum norm, Autoregressive moving average
concluded that at very low SNR, minimum norm is the best in terms of accuracy and stability even though its estimation
variance is very high. It is followed by MUSIC and ARMA in that order.
