Abstract
A wireless communication system includes two wireless communication apparatuses. One of the wireless communication apparatuses wirelessly transmits a signal obtained by up-converting a clock signal. The other of the wireless communication apparatuses generates a clock signal based on a received signal and feeds back a signal obtained by up-converting the generated clock signal to the one wireless communication apparatus. The one wireless communication apparatus generates a clock signal based on the fed-back signal, detects a phase change due to a fluctuation in a transmission path characteristic based on the generated clock signal, and adjusts a phase of a reference clock signal based on the detected phase change.
