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...

Network Coding Theory Via Commutative Algebra
—The fundamental result of linear network coding asserts the existence of optimal codes over acyclic networks when the symbol field is sufficiently large. The restriction to just...

Combinatorial Construction of Locally Testable Codes
An error correcting code is said to be locally testable if there is a test that checks whether a given string is a codeword, or rather far from the code, by reading only a constan...
