Fast-decodable rate-2 MIDO codes from nonassociative algebras
By defining a multiplication on a direct sum of n copies of a
given cyclic division algebra, we obtain new unital nonassociative
algebras.
We employ their left multiplication to construct fully diverse rate-2
space-time block codes for a multiple input-double output system
which are ML-decodable. We give examples of rate-2 fully diverse 4 × 2,
6 × 2, 8 × 2 and 12 × 2 space-time block codes which are fast
ML-decodable. Our approach is a generalization of the one used by Markin
and Oggier.
