Summary:An adaptive precoding method for the aviation communication common channel provided by the invention comprises the following steps of: constructing an aviation communication system in which a base station is configured with a plurality of antennas, and sectorizing each cell in the system; calculating an ideal common channel power directional diagram as a reference power directional diagram; constructing an optimization model of adaptive precoding, namely an optimization model of PBAP; and solving the optimization model of the PBAP to obtain a pre-coding matrix, and completing adaptive pre-coding. The self-adaptive precoding method for the aviation communication common channel provided by the invention has the following two advantages: because the switching of the serving cell usually occurs when the UE is located at the edge of the cell, the PBAP scheme can provide higher signal power for the UE in a switching state, thereby improving the performance of common signal transmission; thePBAP scheme can be used f
