Investigating Ultraharmonic Modeling from Ultrasound Echo Signal with SISO Volterra Filter - 2016
In general, one-input-single-output (SISO) Volterra series can't be used for modeling component of ultraharmonic frequency from ultrasound echo signal. In this paper we gift a brand new technique for modeling the ultraharmonic element based on a SISO Volterra filter with exciting input signal at half-elementary frequency. Results from the approach of the SISO Volterra show capability for successful modeling of the ultraharmonic. We have a tendency to have investigated the accuracy of predicting the ultrasound echo signal under completely different noise levels. Likewise, the SISO Volterra will be still modeled subharmonic frequency component. This is vital solution for separating the ultraharmonic solely or adding each the sub- and ultraharmonic for contrast imaging by the system identification of the SISO Volterra filter.
