Multigroup-Decodable STBCs from Clifford Algebras
A Space-Time Block Code (STBC) in K symbols (variables) is called g-group decodable STBC if its maximumlikelihood decoding metric can be written as a sum of g terms such that each ...

High-rate, Multi-Symbol-Decodable STBCs from Clifford Algebras
It is well known that Space-Time Block Codes (STBCs) obtained from Orthogonal Designs (ODs) are singlesymbol-decodable (SSD) and from Quasi-Orthogonal Designs (QODs) are double-sy...

Registration of 3D Points Using Geometric Algebra and Tensor Voting
Abstract. We address the problem of finding the correspondences of two point sets in 3D undergoing a rigid transformation. Using these correspondences the motion between the two s...

The P-tree algebra
The Peano Count Tree (P-tree) is a quadrant-based lossless tree representation of the original spatial data. The idea of P-tree is to recursively divide the entire spatial data, s...

Almost Tight Upper Bounds for the Single Cell and Zone Problems in Three Dimensions
We consider the problem of bounding the combinatorial complexity of a single cell in an arrangement of n low-degree algebraic surface patches in 3-space. We show that this complex...
