Abstract
Wireless communication channel model is very important in the indoor wireless communication and localization. Presently the vector network analyzer (VNA) usually used as the channel measurement system. There are some elements such as the cable and antennas in the measurement system which need to be calibrated, the calibration method using electric calibration and free space test was given in this work. The analyzation of the measurement focused on the channel attenuation and multipath delay. Because the power-delay profile was measured unclearly, With the Anti — logarithmic transform, the channel multipath delay is much clearer to be obtained. It is better for the calculation of the channel RMS delay spreading. Finally, AR estimator was proposed in this work, and the Normalized Root Mean Square Error of the model was calculated.
