On the Intersection of ${{\BBZ}_{2}{\BBZ}_{4}}$-Additive Hadamard Codes
Josep Rifà, F. I. Solov’eva, Mercè Villanueva · IEEE Transactions on Information Theory · 2009
The intersection structure forZ2Z4-additive Hadamard codes is investigated. For any two of these codesC1andC2, the Abelian group structure of the intersectionC1capC2is characterized. The parameters of this Abelian group structure corresponding to the intersection codes are computed, establishing lower and upper bounds for them. Constructions are given of codes whose intersection has any parameters between these bounds.
