Results of computer simulation tests of the STBC Alamouti MIMO 2×2 system in comparison to SISO were presented in this paper. The aim was to assess effectiveness of MIMO versus SISO in assumed propagation conditions. Depending on subscriber motion, propagation conditions as well as antenna system configuration, different results were received. In each configuration, MIMO system was not worse than SISO and many times it is significantly better than SISO with gain from a few to a dozen or so dB.

W artykule zaprezentowano wyniki symulacji komputerowej systemu wieloantenowego MIMO 2×2 (ang. Multiple Input Multiple Output) z koderem STBC (ang. Space Time Block Coding) Alamoutiego w porównaniu do systemu SISO (ang. Single Input Single Output). Celem badania było określenie stopnia efektywności układu MIMO zależnie od prędkości i kierunku ruchu korespondenta, warunków propagacji oraz konfiguracji anten. Zależnie od założeń symulacyjnych uzyskano wyniki potwierdzające przewagę MIMO nad SISO w zakresie od kilku do kilkunastu dB.
