Characteristic Analysis of Wireless Signal in Micro-cellular Environment |

| Abstract: | As the recent development of mobile communications,the micro cells and pico cells are widely deployed for the purpose of high spectral efficiency which result in the difference of the characters of statistic.The ray tracing model is adopted to analyze the distribution of wireless channel in this essay.In terms of finding the transmission routes between transmitter and receiver,the qualified ray tracing algorithm and virtual mirror source tree algorithm are considered.We also build equivalent baseband analysis model based on the ray tracing results and investigate the interference of different transmission signal streams.Last but not least,numerical analysis verifies the accuracy of our models with the routing information obtained by ray tracing. |
