Provided is a method that includes dynamically adjusting a GPS signature code to minimize the interference (e.g., the cross-correlation interference) experienced due to one or more other GPS signals. Further provided is a method that includes adjusting the complexity of an adaptive solution to reduce the time and processing power associated with tracking a GPS signal.

The invention relates to the field of user portraits, and discloses a transaction mode portrait establishing method and device, a medium and an electronic device. The method comprises the steps of obtaining a sample set comprising a plurality of intermediate accounts and feature value groups corresponding to the intermediate accounts; obtaining clustering features in a preset feature group according to the feature value group; obtaining a feature value corresponding to the clustering feature as a clustering feature value; clustering the intermediate accounts based on the clustering feature values, and dividing the intermediate accounts into a plurality of clusters; determining a transaction mode corresponding to the cluster according to the clustering feature value of the intermediate account in the cluster; when a request for establishing a transaction mode portrait of a target intermediate account is received, obtaining a feature value group of the target intermediate account; and determining a transaction mode of the target intermediate account based on the feature value corresponding to the clustering feature in the target intermediate account feature value group and the transaction mode corresponding to each cluster. According to the method, the accuracy of the transaction mode portrait is ensured, and the meticulous degree of depicting the transaction mode portrait is improved.
