Space-time block codes which can be identified as rings: Twisted group algebras of small groups

Research output: Contribution to journalArticle


In this paper, we give a general criterion to determine when a complex space-time block code has a ring structure and then we provide a complete list of complex space-time block codes which have ring structures up to size 4.
