| Abstract: | The calculation of scattering function of high frequency channel was analyzed theoretically and the measure method of scattering function in high frequency channel sounding experiment was provided. Then the estimation methods of the parameters such as fading bandwidth, fading correlation time, multi - path disperse, correlation bandwidth of high frequency channel and the Doppler shift, delay time of high frequency signal by scattering function were given. The scattering function of high frequency channel was obtained from experiment data and the parameters related above were estimated by it. At the same time, parameters estimation results were provided. |
