Abstract
A calibration method for achieving channel reciprocity is provided. The method is used in a wireless communication device and includes: receiving environment information between a root node and each of a plurality of child nodes and between each of the child nodes and one of the other child nodes transmitted by the root node and the child nodes; obtaining evaluation parameters between each of the child nodes and the root node and between each of the child nodes and one of the other child nodes according to the environment information; determining links between the root node and the child nodes according to the evaluation parameters to form a first tree network topology; and obtaining calibration parameters according to the first tree network topology to calibrate reciprocity of the root node and the child nodes.
