Method and device for wireless network optimization in high-speed scene of high-speed railway

The invention provides a method and device for wireless network optimization in a high-speed scene of the high-speed railway. The method comprises the steps of obtaining the reference signal transmitting power of a signal reception sampling point, calculating the antenna gain of the signal reception sampling point, the path loss of radio wave propagation of a transmitting antenna and the penetration loss of radio waves transmitted by the transmitting antenna; obtaining the reference signal receiving power (RSRP) received by a signal receiving terminal according to the reference signal transmitting power, the antenna gain, the path loss and the penetration loss; obtaining the sweep frequency RSRP, and fitting the sweep frequency RSRP and the reference signal receiving power (RSRP) to obtaina fitting environment factor and fitting path loss, constructing a radio wave transmission model in the high-speed scene of the high-speed railway; and optimizing a wireless network in the high-speedscene of the high-speed r
