摘　　要：针对几公里范围的军事通信,在经验测试数据的基础上建立了的超宽带冲激无线电(UWB-IR)室外通信的信道模型,通过仿真对在该模型条件下通信系统的误码性能进行了分析,并利用化简和近似求解的方法,对其容量进行了分析和计算。For military communication in a range of a few kilmetres, a channel model of outdoor UWB-IR is established on the basis of empirical data. By utilizing this model, the performance of UWB-IR communication systems is analyzed. Furthermore, the channel capacity is calculated and discussed by means of equation simplification and approximate solution.
