摘要
本文首先分析隧道环境下无线数字通信信道的研究现状,指出研究中应充分利用计算机仿真手段,给出隧道无线电射线传输所遵循的帐篷定律,介绍各次射线传输距离的迭代算法,为隧道无线传输信道的计算机仿真提供了一种较为系统的方法。
The research work on radio digital communication channel in tunnel environment was analyzed. The conclusion that computer simulation should be adopted in the research was presented. Tent Law that describes the transmitting characteristic of radio ray in rectangular tunnel was given. The iterating algorithm for calculating the distance of each reflected path was discussed. A systematic simulating method for radio data transmission in tunnel was built.
