On MIDO Space-Time Block Codes

Camilla Hollanti, Kalle Ranto, On MIDO Space-Time Block Codes. In: Proceedings of the 2007 IEEE International Symposium on Information Theory ISIT, 2007.

Abstract:

In this paper, the need for the construction of multiple input-double output (MIDO) space-time block codes (STBCs) is discussed, concentrating on the case of four transmitters for simplicity. Above the trivial puncturing method, i.e. switching off the extra layers in the usual multiple input-multiple output (MIMO) setting, two other, more sophisticated yet simple MIDO construction methods are proposed. The use of these general methods is then demonstrated by building explicit, sphere decodable codes using two different cyclic division algebras (CDAs). We verify by computer simulations that the newly proposed methods can compete with the puncturing method, and in some cases outperform it. Our best construction exploiting maximal orders improves even upon the punctured perfect code and the DjABBA code.
