  • Patent number: 8989305
    Abstract: Disclosed herein are a method and apparatus for generating multiband Radio Frequency (RF) signals in maritime wireless communication. The apparatus includes a baseband conversion unit, a phase compensation unit, a Direct Current (DC) offset compensation unit, and an RF transmission unit. The baseband conversion unit converts RF signals corresponding to a baseband modulation signal having a negative frequency and a baseband modulation signal having a positive frequency into baseband signals, respectively. The phase compensation unit eliminates the images of multiband signals so as to correspond to the baseband signals. The DC offset compensation unit compensates the baseband modulation signals for DC offsets using the multiband signals from which the images have been eliminated. The RF transmission unit generates the RF signals using the signals which have been compensated for the DC offsets, and sends the RF signals via an antenna.

  • Publication number: 20140146810
    Abstract: The present invention relates to a method and apparatus in which an Automatic Identification System (AIS) accesses a radio channel. The present invention includes selecting a slot on which a packet is to be transmitted on at least one radio channel, temporarily sending a first carrier, notifying other AISs that the selected slot has been selected by the AIS, on the selected slot in transmission mode, and after temporarily sending the first carrier, detecting a second carrier transmitted by another device on the selected slot in reception mode. In accordance with the present invention, the AIS temporarily sends a first carrier, notifying other AISs that a selected slot has been selected by the AIS, on the selected slot prior to the detection of a second carrier, and another AIS accessing the same slot detects the first carrier temporarily transmitted. Accordingly, a collision between channels can be avoided.

  • Patent number: 8571008
    Abstract: The present invention relates to a time synchronization method in a wireless sensor network. In the present invention, if an upper node requests a lower reference node to start time synchronization, the lower reference node broadcasts a first sync reference packet. The upper node receives the first sync reference packet and transmits the first sync reference packet reception time to the lower reference node. The lower reference node broadcasts the first sync reference packet reception time, such that the other nodes perform time synchronization on the basis of the first sync reference packet reception time. Meanwhile, the lower reference node estimates the first sync reference packet reception time of the upper node to calculate the reception estimation time, and transmits the reception estimation time to a determination node that is two hops anterior to the lower reference node.
