Software Solutions for Converting a MIMO-OFDM Channel into Multiple SISO-OFDM Channels
We present a software approach for MIMO-OFDM wireless communication technology. We first show that complex matrix operations like Singular-Value Decomposition (SVD), diagonalizat...

On the Complexity of Matrix Rank and Rigidity
We revisit a well studied linear algebraic problem, computing the rank and determinant of matrices, in order to obtain completeness results for small complexity classes. In partic...

Extended Timed Automata and Time Petri Nets
Timed Automata (TA) and Time Petri Nets (TPN) are two well-established formal models for real-time systems. Recently, a linear transformation of TA to TPNs preserving reachability...

Steganalysis based on Markov Model of Thresholded Prediction-Error Image
A steganalysis system based on 2-D Markov chain of thresholded prediction-error image is proposed in this paper. Image pixels are predicted with their neighboring pixels, and the ...
