摘要： Provided is a synchronization system and method for acoustic communication in audible frequency range, and an apparatus applied thereto. The synchronization system for acoustic communication in audible frequency range is configured to prevent deterioration of a synchronization performance and to reduce an amount of calculation by calculating a correlation based on a few samples as opposed to calculating a correlation for each sample when a receiver of the acoustic communication performs synchronization while the acoustic communication is performed in the audible frequency range through modification of an audio signal or adding of a predetermined signal to an audio signal.

摘要： The present invention relates to a system and to a method for QoS (Quality of Service) support in a ubiquitous sensor network. The system for QoS support in a ubiquitous sensor network includes a mesh coordinator and nodes. The mesh coordinator organizes a super frame containing a dedicated QoS data transmission period, and synchronizes each of the nodes constituted into one network with the abovementioned super frame. The nodes create a beacon frame containing information on whether or not to set QoS, to broadcast the beacon frame in a dedicated beacon period of the super frame if QoS data transmission is needed, to create a QoS data frame with a set priority, and to transmit the QoS data frame to the dedicated QoS data transmission period of the super frame in the case of transmitting QoS data. The present invention divides QoS data from general data to improve the quality of data transmission and ensure stability, and prioritizes QoS data to transmit the most important data among QoS data in a quick and stable manner.

摘要： Disclosed is a multicast system and a multicast method using a shortened address and an apparatus applied to the same. The multicast system using the shortened address according to the present disclosure has a address configuration for supporting a multicast in an IEEE 802.15.4 MAC (Medium Access Control) layer. Accordingly, when a device processes a multicast through an address configuration of the MAC layer, the device receives the multicast through a simple scheduling such as receiving a beacon signal of a coordinator device only when there is a broadcast of a group including the device. As a result, the device can efficiently perform the multicast in a power managing process or a power processing process.

摘要： The present invention relates to a method and to a wireless personal area network (WPAN) device in which the device sets the beacon slot in the WPAN device and receives beacon slot information from neighbor devices, while setting the beacon table of the devices, to avoid the transmission time of the neighbor devices and the transmission time of the devices neighboring the neighbor devices in a WPAN. In the method, beacon message, including information about neighbors' transmission time and information about neighbors' neighbors' transmission time, is received from neighbor devices. The beacon message is combined, and the neighbors' transmission time information and the neighbors' neighbors' transmission time information are input into a beacon table. The neighbors' transmission time and the neighbors' neighbors' transmission time are input into a field for BTTSs to be avoided in the beacon table. The first beacon slot is set, as my beacon transmission slot, among beacon slots except for the transmission time input into the field for BTTSs to be avoided. Information about the set beacon transmission slot is input into a field for my BTTS in the beacon table.

摘要： Provided is a data reception error reduction system and method in acoustic communication in audible frequency range, and an apparatus applied thereto. The data reception error reduction system in the acoustic communication in audible frequency range may be configured to reduce a data reception error in a receiver by taking into consideration that a sound signal is noisy and is significantly affected by a change in the ambient environment when the acoustic communication is performed in the audio frequency band through modification of an audio signal or adding of a predetermined signal to an audio signal. Accordingly, the data reception error may be reduced in the receiver even in an environment where a sound signal is noisy and is significantly affected by a change in the ambient environment, and reliability of data transmission may increase.
