Abstract

The multiple input multiple output (MIMO) technology increases the capacity of wireless communication system remarkably. However, it is unrealistic to deploy distributed antenna system (DAS) owing to several problems, including power imbalance, frequency difference and time delay difference between different data streams. In this paper, we analyze MIMO system capacity theoretically at first. Then we analyze effects of the problems above on MIMO system performance. At last, we conduct LTE link level simulation to verify our assumptions and draw our conclusions.
