WebThis was also a nice opportunity to implement an online version of the AuxIVA variant from a recent publication of our lab. We use the direct form (and not the Woodbury-lemma version) of the algorithm. 3x3 cases can be separated real-time on a passive-cooled, not-overclocked Raspberry Pi 4, though it has been hard to achieve glitch-free ... WebIn experiments, AuxIVA applied in the whole frequency range is compared with the proposed approach. The results show that the latter can be twice faster than AuxIVA without loosing much in terms of the separation accuracy. In some cases where the separation accuracy achieved by AuxIVA is poor the proposed approach improves the separation, … browned steel
