Abstract :
In cellular mobile communications, multipath fading, shadowing, near-far problem and the Doppler effect have led to a complex radio wave propagation environment. Furthermore, with the continuously increasing of users and operations, not only new bandwidth is required, new technologies and measures are also expected to improve the system capacity and channel capacity. This paper introduces the general structure of multi-antenna communication systems firstly, then analyzes the characteristics of various multi-antenna technologies and their advantages over single antenna system when applied in cellular mobile communications. Finally, combined with the trends and requirements of cellular mobile communications, the further application of multi-antenna technologies in future cellular mobile communications is prospected.
