Improvement to esprit-type frequency estimators via reducing data redundancy
In this paper, the problem of estimating the damping factor and frequency parameters from multiple cisoids in noise is addressed. We rst propose a data matrix which generalizes th...

Practical Near-Collisions and Collisions on Round-Reduced ECHO-256 Compression Function
In this paper, we present new results on the second-round SHA-3 candidate ECHO. We describe a method to construct a collision in the compression function of ECHO-256 reduced to fou...
