Multiple-input multiple-output (MIMO) systems have been extensively studied over the last decade because they provide high data-rate transmission without increasing the frequency bandwidth. They have already been in practical use in wireless local area networks (WLANs) and the long term evolution (LTE) of cellular networks. A MIMO system is one of the applications of space-domain signal processing. On the other hand, an adaptive antenna can suppress interference and realize a diversity effect. An adaptive antenna is a simpler application of space-domain signal processing. In this talk, we will share the basic concept of the space-domain signal processing with the audience. Then, this presentation will introduce the space division multiple access (SDMA) for the Personal Handy-phone System (PHS) using the adaptive antenna. Furthermore, we will discuss some important features of MIMO systems.
