The method can improve the precision of time synchronization. The method comprises the following steps: receiving a first signal from a master node by a slave node; sampling a first signal from a node to obtain first samples; quantizing the first sample from the node to obtain a quantized version of the first sample; detecting a first synchronization sequence from the quantized version of the first sample by the slave node, wherein the time for detecting the first synchronization sequence is T2; the slave node receives first information from the master node, wherein the first information is used for indicating the time T1 when the master node sends the first synchronization sequence; the slave node sends a second synchronization sequence to the master node, and the time for sending the second synchronization sequence is T3; receiving, by the slave node, second information from the master node, the second information indicating a time T4 at which the master node detected a quantized version of the second synchronization sequence; the slave nodes are time synchronized according to T1, T2, T3, and T4.)
