报告摘要：To support the growing demand for wireless traffic, wireless networks are becoming more dense and complicated, leading to a higher difficulty to derive the capacity. In this paper, we propose a fast algorithm TOSE to estimate the capacity for ultra-dense wireless networks. Our algorithm can avoid the exact eigenvalue derivations of large dimensional matrices, which are complicated and inevitable in conventional capacity calculation methods. Instead, fast eigenvalue estimations can be realized based on the spike approximations in our TOSE algorithm. Our simulation results show that TOSE is an accurate and fast capacity approximation algorithm. In addition, TOSE has superior generality, since it is independent of the distributions of BSs and users, and the shape of network areas.
