PROBLEM TO BE SOLVED: To allow for maintenance of time synchronization between communicators, when the communication is interrupted or degraded by shielding, or the like, in the wireless communication performing beam forming.SOLUTION: When performing communication between communicators having a directivity control function, a plurality of antenna setting pairs available for communication by initial training are stored, and communication is started using one of the plurality of antenna setting pairs. Upon occurrence of communication quality degradation, a training signal is transmitted to the transmission antenna of one communicator (400), while a plurality of antenna setting candidates determined by initial training are sequentially set, and received by the receiving antenna of the other communicator (500) with a pseudo-omni pattern being generated. |
