【摘要】 本文研究了两个异步DS-UWB通信系统同时工作时,系统间的彼此干扰问题．仿真结果表明:两个异步DS-UWB通信系统间的干扰主要取决于两个系统的码片速率,高速率系统对低速率系统干扰严重,此时可通过适当增加低速率系统扩频码长度来抑制干扰。更多还原

【Abstract】 In this paper, we study the intra-system interference of two coexistent DS-UWB asynchronous communication systems. The simulation result shows that interference between two systems lies on the code rate .When two asynchronous DS-UWB communication systems work together, the high-rate system generally does more harm to the low-rate system and such intra-system interference can be restrained by increasing the length of pseudo noise (PN) codes.更多还原
