| Abstract: | First, the basic principle of MIMO wireless system is briefly described in flat-fading wireless channel. Then, we concentrate on discussing three crucial techniques of MIMO system as follows: channel modeling, space-time coding, and the design of MIMO receiver. At the same time, MIMO technique is shown to have the following four advantages: array gain, space diversity, space multiplexing, and interference reduction. Thus, we predict that MIMO technique will certainly achieve an extensive range of applications in future wireless accesses such as wireless local network (WLAN), and 4G mobile communication systems. |
