| Abstract: |
| An improved ray-tracing model based on traditional microwave propagation prediction models is presented . This model can be really used to predict propagation precisely in complicated micro-cell domain formed by multi-edges and corners buildings except circular buildings, which is provided with many advantages such as high self adaptation, prediction preciseness can be controlled by demands and high efficiency. The prediction results by this improved model are compared with references, which indicates the improved model bears higher efficiency and precision. |
