Iterative frequency domain channel estimation for dft-precoded ofdm systems using in-band pilots
We consider two techniques of in-band frequency domain multiplexed (FDM) pilots using interleaved frequency domain multiple access (IFDMA) signal with a Chu sequence for DFT-precod...

A Computational Model for RNA Multiple Structural Alignment.
Abstract. This paper addresses the problem of aligning multiple sequences of non-coding RNA genes. We approach this problem with the biologically motivated paradigm that scoring of...

Tracking of Multiple Faces for Human-Computer Interfaces and Virtual Environments
In this paper, we describe a real-time face-tracking algorithm. We start with single face tracking based on statistical color modeling and the deformable template. We then expand ...

Simplicial cycles and the computation of simplicial trees
We generalize the concept of a cycle from graphs to simplicial complexes. We show that a simplicial cycle is either a sequence of facets connected in the shape of a circle, or is ...
