Algebraic Constructions of Space-Frequency Codes
— Recently an algebraic construction of (nt × Q) space-frequency (SF) codes over finite field Fq was proposed for use in MIMO-OFDM systems, where nt is the number of transmit ...

Distributed Source Coding Using Syndromes (DISCUS): Design and Construction
We address the problem of distributed source coding, i.e. compression of correlated sources that are not co-located and/or cannot communicatewith each other to minimize their join...

Hadamard matrices of order 32 and extremal ternary self-dual codes
A ternary self-dual code can be constructed from a Hadamard matrix of order congruent to 8 modulo 12. In this paper, we show that the Paley-Hadamard matrix is the only Hadamard ma...

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...

Codes for asymmetric limited-magnitude errors with application to multilevel flash memories
Several physical effects that limit the reliability and performance of multilevel flash memories induce errors that have low magnitudes and are dominantly asymmetric. This paper st...
