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...

The consistency strength of choiceless failures of SCH
We determine exact consistency strengths for various failures of the Singular Cardinals Hypothesis (SCH) in the setting of the Zermelo-Fraenkel axiom system ZF without the Axiom o...

Algebraic solutions of holomorphic foliations: An algorithmic approach
We present two algorithms that can be used to check whether a given holomorphic foliation of the projective plane has an algebraic solution, and discuss the performance of their im...

Channel Orthogonalizing Precoder for Open-Loop QO-STBC Systems
—This paper proposes a new preprocessing scheme for rate-one quasi-orthogonal space-time block code (QO-STBC), which requires no channel state information at the transmitter. We ...

Diversity Analysis of coded SVD Schemes for MIMO Spatial Multiplexing Systems
— When channel state information (CSI) is available at both transmit and receive sides, singular value decomposition (SVD) converts the MIMO channel into parallel subchannels. It...
