摘要： When communication is to be performed between communication devices having a directivity control function, a plurality of antenna-setting pairs available for the communication are stored by an initial training, and the communication is started by using one of the plurality of antenna-setting pairs. When the communication quality is deteriorated, firstly, a training signal is transmitted while successively setting each one of the plurality of antenna-setting candidates determined in the initial training in a transmitting antenna of one of the communication devices (400), and the training signal is received in a state where a quasi-omni pattern is generated in a receiving antenna of the other communication device (500). In this way, in radio communication performing beam forming, it is possible to ensure the time synchronization between the communication devices when communication is disconnected or communication quality is deteriorated due to shielding or the like.

摘要： A channel response matrix is obtained by performing a training process between a transmitter 401 and a receiver 402 to obtain optimal signal phases of the antenna array. Next, a singular-value decomposition (SVD) process is performed to decompose the channel response matrix into a correlation matrix and eigenvalues. Next, a diagonal matrix having square roots of the eigenvalues as its components is obtained. Next, all but one of diagonal components included in the diagonal matrix are replaced with zeros, and optimal setting of the amplitudes and phases of signals to be applied to the antenna array (antenna weight vector) for use in wireless communication between the transmitter and the receiver is obtained based on a channel response matrix that is reconstructed by using the component-replaced diagonal matrix. In this way, when wireless communication is implemented by performing beam forming, the time necessary to find and set a beam direction can be reduced.

摘要： A method of controlling a wireless communication system including a plurality of communication devices is disclosed. In the method, firstly, one of the communication devices establishes a fixed beam pattern and transmits a training signal, and another communication device receives the training signal while scanning a beam direction by changing the AWVs of an antenna array. Next, it obtains a data string describing a relation between an incoming direction and a received-signal characteristic at the other communication device based on a reception result of the training signal. Then, it obtains first AWVs with which a beam is formed in a plurality of incoming directions of the received signal based on the data string. The roles of these two communication devices are interchanged and similar processes are performed in order to obtain second AWVs, and then one of AWV combinations combining first and second AWVs are used for wireless communication between these communication devices.

摘要： A communication device 1 (transceivers 400) transmits a training signal from its own transmitting antenna while performing beam scanning, and a communication device 2 (transceivers 500) receives this training signal in a state where a quasi-omni pattern is generated in its own receiving antenna. Further, the device 1 transmits a training signal in a state where a quasi-omni pattern is generated in the transmitting antenna, and the device 2 receives this training signal by the receiving antenna while performing beam scanning. The device 1 and 2 detects, from respective reception results, transmitting-antenna-setting candidates of the device 1 and receiving-antenna-setting candidates of the device 2, and determines antenna-setting pairs (combinations of antenna-setting candidates). The above-described processes are also performed for a receiving antenna of the device 1 and a transmitting antenna of the device 2. The device 1 and 2 communicates by using the obtained antenna-setting pairs. In this way, when radio communication is performed by using beam forming, the time necessary for finding and setting a beam direction is reduced, thereby reducing the transmission-disconnected time.

摘要： To suppress adverse effects caused by side lobes of an antenna array when an AWV to be used for communication is determined based on a transmission/reception result of a training signal. A first transceiver generates a fixed beam pattern and transmits a training signal. In that state, a second transceiver receives the training signal while scanning for the main beam direction, and thereby determines a plurality of direction of arrivals (DOAs). Next, the second transceiver receives the training signal in a state where the signal receptions from the plurality of DODs are restricted one by one (e.g., a null direction or a direction close to the null direction is fixed in the DOA), and calculates the change of the signal characteristics from that obtained in the first reception. The transceivers obtain and use at least one AWV having the main beam direction or a sub-beam direction close to the main beam pointing to one of the plurality of DOAs except for the DOA for which the change is lower than a predefined threshold.

摘要： To suppress an adverse effect caused by side lobes of an antenna array when determining an AWV to be used in communication. A first communication device transmits/receives a training signal while scanning a beam pattern, and a second communication device receives/transmits the training signal with a fixed beam pattern. A primary DOD/DOA in the first communication device is determined based on the transmission/reception result of the training signal. Then, second round training is performed. In this point, the first communication device transmits/receives the training signal while scanning a beam pattern in a state where transmission to the primary DOD or reception from the primary DOA is restricted. A secondary DOD/DOA is determined based on the result of the second round training. An AWV corresponding to the primary DOD/DOA and an AWV corresponding to the secondary DOD/DOA are selectively used in communication between the first and second devices.

摘要： A communication quality test is performed for combinations between antenna setting candidates of a transmitting antenna of a first communication device (1) and a receiving antenna of a second communication device (2), and a list in which antenna-setting pairs are arranged according to the communication quality is created. If there are two or more antenna-setting pairs having the same antenna setting for one of the transmitting and receiving antennas, it is determined that an antenna-setting pair(s) ranked in a second or lower place is caused by a side-lobe and thus the list is updated by deleting that antenna-setting pair(s) from the list or lowering its priority rank in the list. The above-described steps are performed for a receiving antenna of the first communication device (1) and a transmitting antenna of the second communication device (2). An antenna-setting pair is successively selected from the updated antenna-setting-pair list and communication is performed.
