Abstract :
For cellular networks, the users´ location and transmit power greatly influence the strength of interference caused to neighbor cells. In this paper, we theoretically analyze the approximate sum rate performance of singular value decomposition and interference alignment transmission strategies. Based on the analysis, a novel combined transmission strategy using strategies selection is presented to improve the system performance. And this novel combined transmission strategy could highly reduce the system complexity and the demand of instant channel state information.
