Multiple-Input Multiple-Output (MIMO) communication techniques have been an important research topic due to their potential for high capacity, increased diversity, and interference suppression. For applications such as wireless LANs and cellular telephony, MIMO systems will likely be deployed in environments where a Base Station (BS) simultaneously communicates with many users. As a result, the study of MultiUser MIMO (MU-MIMO) systems has recently emerged as an important research topic. Such systems have the potential to exploit the high capacity achievable by MIMO processing and combine this with the benefits of Space Division Multiple Access (SDMA).
