An antenna control device includes a weight unit in which weight values to be superimposed on transmission/reception signals are set for forming radiation patterns using a plurality of antennas and a weight synthesis unit that superposes the weight values on the transmission/reception signals. The antenna control device further includes an arrival direction detector that detects arrival directions of the reception signals, a distribution information calculator that calculates distribution information of the detected arrival directions, a signal quality calculator that calculates signal quality information of each of the radiation patterns, and a radiation pattern selector that selects a radiation pattern on the basis of the distribution information and signal quality information for the radiation patterns, and sets the weight values corresponding to the selected radiation pattern in the weight unit.

Autonomous radiation pattern generation antenna control device, control method therefor, and wireless communication system

A public key of a sensor node key pair is transmitted from a sensor nodeto a servervia sensor network communication, and furthermore is transmitted from the serverto a mobile terminalvia mobile line communication. In addition, a public key of a mobile terminal key pair is transmitted from the mobile terminalto the sensor nodethrough local communication. Thus, the configuration allows the sensor nodeand the mobile terminalto generate a common key by combining their own private key and the public key of the counterpart in order to encrypt the local communication by using this common key.

Communication system

A broadcast wave synchronization signal converting device that synchronizes broadcast waves with GNSS signals on a reception side and corrects the broadcast waves to global standard times by use of correction values, thereby performing periodic calibrations of frequencies. The broadcast wave synchronization signal converting device includes: a PLL circuit reproduces system clocks on the basis of time information acquired from received broadcast waves; a subtractor (C) subtracts, from a counter value corresponding to the periodic signal intervals of GNSS signals, a counter value of the system clocks counted at the signal intervals and outputs the difference value; a control amount adjustor calculates a control amount of synchronization as a correction value on the basis of the difference value; and a subtractor (B) subtracts the correction value from the acquired time information and sets the corrected time information to a PCR counter as the internal time information thereof.

Broadcast wave synchronization signal converting device
