Dynamic signal in wireless link is often interfered. So there is a huge challenge when wireless link is estimated. In this paper, multi-path fading is introduced into wireless channel and used to analyze bit error rate of wireless link. Then a reality link quality estimating model is built by integrating noise, shadow fading and multi-path fading. The problem that the existing model is too ideal is solved. The model built has the good expansibility to a certain extent. And it can be applied to different environment by changing corresponding parameters.
