Unitary subgroup space-time codes using Bruhat decomposition and Weyl groups
T. Konishi · 2003
This paper is proposed new untiary subgroups for differential space-time codes. The subgroups are constructed on the basis of double coset decomposition, Bruhat decomposition. Also, we give some examples of the proposed subgroup space-time codes, and describe how the new codes are combined with coded modulation systems.
