Underdetermined mixing matrix estimation based on artificial bee colony optimization and single-source-point detection

X He, F He - Multimedia Tools and Applications, 2020 - Springer
It is difficult to solve the problem of underdetermined blind source separation (UBSS) since
the mixing system is not invertible. Therefore, estimating the underdetermined mixing matrix …

Spatial gradients of geomagnetic temporal variations causing the instability of inter-station transfer functions

S Sato, T Goto, K Koike - Earth, Planets and Space, 2020 - Springer
Spatial gradients in the primary geomagnetic fields directly contribute to both the amplitudes
and phases of inter-station transfer functions (IS-TFs). This suggests that, for the analysis of …
