MIMO信道仿真器相对路径衰减校准方法的研究
Study on the Calibration Method for Relative Path Attenuation of MIMO Channel Simulator
摘要
Abstract
The channel power delay profile is measured using channel estimation techniques and therefore relative path attenuation of MIMO channel simulator is calibrated.The calibration system is traceable with the standard network which is made of delay line and attenuator.The experiment results show that the range of calibrating relative path attenuation is from 0 to-25 dB.At 500 MHz radio frequency and 300 ns relative path delay point,the expanded uncertainty of relative path attenuation is 0.35 dB(k =2).关键词
