The method comprises: determining a window length of an attenuating window of a current frame according to an inter-channel time difference of the current frame (310); determining a corrected linear prediction analysis window according to the window length of the attenuating window of the current frame, wherein values of at least some of the points between an (L−sub_window_len)th point and an (L−1)th point in the corrected linear prediction analysis window are lower than values of corresponding points between the (L−sub_window_len)th point and the (L−1)th point in an initial linear prediction analysis window, sub_window_len is the window length of the attenuating window of the current frame, L is a window length of the corrected linear prediction analysis window, and the window length of the corrected linear prediction analysis window is equal to the window length of a linear prediction analysis window of the current frame (320); and performing linear prediction analysis on a channel signal to be processed according to the corrected linear prediction analysis window (330). The accuracy of linear prediction can be improved.

Abstract: A positioning model building method, the method comprising: acquiring a measurement report set of a target cell; determining a corresponding example data group according to each measurement report; encoding the example data group corresponding to each measurement report into a training sample corresponding to each measurement report, wherein a sample label of each training sample is geographical coordinates, carried by the corresponding measurement report, of a terminal; and training the training sample corresponding to each measurement report in the measurement report set and a sample label corresponding to each training sample so as to obtain a local positioning model of the target cell. In a subsequent positioning process, after a sample to be identified is acquired according to a measurement report to be identified, the corresponding geographical coordinates can be obtained by means of computation according to the local positioning model of a cell corresponding to the sample to be identified, which has the advantage of fast positioning speed. The present application also provides a positioning model building device capable of implementing the method. In addition, the present application also provides a wireless positioning method and device.
