Design of multipath channel measurement system in wireless sensor network

文中基于现有测量仪器搭建了一套多径信道的一种实时测试系统,并通过搭建的系统测试了无线信道仿真仪的多径分布情况。该方法抗干扰性强,具有准确度高、实时性强的优点。仿真测试结果表明基于该方法搭建的测试系统能够有效地测试外场多径信道的分布情况,并能够持续反映多径信道的变化情况。

This paper builds a real-time test system based on the existing measuring instruments to measure a multi-path channel. And it tests the distribution of wirelesschannel emulatorby the proposed system. This method interference is strong, with a high degree of accuracy, timeliness strong. The simulation results show that this method can set up a test system, which effectively tests the distribution of outfield multipath channel and be able to continue to reflect changes in the multi-path channel.
