A singular value decomposition-based extraction algorithm is designed in order to recover the group velocity of an energetic contribution measured with an axial transmission device developed previously for cortical bone assessment. Its performance is evaluated on synthetic data mimicking in vivo signals, and it is compared with classical methods.
