Faster GPS via the sparse fourier transform
GPS is one of the most widely used wireless systems. A GPS receiver has to lock on the satellite signals to calculate its position. The process of locking on the satellites is qui...

Floquet transformations for discrete-time systems: Equivalence between periodic systems and time-invariant ones
— This paper considers discrete-time periodic linear systems and their Floquet transformations, by which the periodic systems can be equivalently transformed to time-invariant on...

Analysis of Second-Order Modes of Linear Continuous-Time Systems under Positive-Real Transformations
Abstract— This paper discusses the behavior of the secondorder modes of linear continuous-time systems under variable transformations with positive-real functions. We first disc...
