Recursive blind channel identification and equalization by ULV decomposition

Most eigenstructure-based blind channel identi cation and equalization algorithms with second-order statistics need SVD or EVD of the correlation matrix of the output signal. In this paper, we show new algorithms based on QR factorization of the output data directly. A recursive algorithm is developed by updating a rank-revealing ULV decomposition. Compared with existing algorithms in the same ...

Eigenstructure Assignment Algorithm for Mechanical Second-Order Systems

Introduction E IGENSTRUCTURE assignment algorithms are widely used to design control systems.Most of the available eigenstructure assignment algorithms assign all of the eigenvalues to the desired values.The eigenstructureassignmentalgorithmcan be dividedinto two groups, that is, the null space approach and Sylvester equation approach.The null spaceapproachis used to solvemode decoupling proble...

Enforcing RBAC Policies over Data Stored on Untrusted Server (Extended Version)

One of the security issues in data outsourcing is the enforcement of the data owner’s access control policies. This includes some challenges. The first challenge is preserving confidentiality of data and policies. One of the existing solutions is encrypting data before outsourcing which brings new challenges; namely, the number of keys required to access authorized resources, efficient policy u...
