Contrast Improvement in Sub- and Ultraharmonic Ultrasound Contrast Imaging by Combining Several Hammerstein Models

Figure 8

Variation of RMSE in dB between the backscattered signal by the contrast agent and that modeled with (blue) the standard Hammerstein model, (black) method  1, and (green) method  2 as a function of the memory of Hammerstein model in presence of output noise:  dB,  dB,  dB, and  dB.
