Adaptive Filtering via Canonical Systems with Time-Varying Hamiltonians
Keshav Raj Acharya, Pitambar Acharya
In many practical applications, signals and environments are time- varying, which makes fixed filters unreliable. Adaptive filtering, on the other hand, updates in real time to sup…

2N-Dimensional Canonical Systems and Applications
Keshav Raj Acharya, Andrei Ludu
We study the 2N-dimensional canonical systems and discuss some properties of its fundamental solution. We then discuss the Floquet theory of periodic canonical systems and observe…
