Abstract:

The introduction of small cells not only brings a substantial increase of network coverage and capacity, but also results in a more complex wireless environment. A small cell performance evaluation method based on improved fuzzy analytic hierarchy process (FAHP) is proposed. A hierarchical model of small cells is established. Factors which impact the performance of the small cell are analyzed. Measuring and quantitative methods of indicators in small cells are presented combined with the fuzzy mathematical theory. The weighting approach of each indicator based on FAHP is improved to get the performance evaluation results of each small cell scheme. Simulation results show that the proposed method can select the optimum one from some different small cell configuration programs, providing a good reference for the deployment of small cells.
