Mobile equipment position estimation method based on multi-base-station channel state information fusion

The invention discloses a mobile equipment position estimation method based on multi-base-station channel state information fusion, and belongs to the technical field of radio mobile positioning. The method comprises the following steps: enabling a base station to collect a non-real-time channel state information sample from mobile equipment; extracting angular domain power spectrum channel characteristics; calculating the difference degree between the samples according to the angular domain power spectrum channel characteristics to obtain a single base station sample difference degree matrix; enabling a data fusion node to fuse the plurality of single base station sample difference degree matrixes to obtain a global sample difference degree matrix; enabling the data fusion node to create a channel map for the sample data set according to the global sample difference degree matrix, and calibrate the channel map; and enabling the base station to collect real-time channel state information from the mobile equip
