Abstract: An array speaker system is provided to obtain an effect of a plurality of sound sources by using a small number of sound sources without the lowering of the performance of the speaker by forming a plurality of sound holes. An array speaker(310) is comprised of a plurality of speakers. A plurality of sound holes are formed in a speaker cover(320). The plurality of sound holes radiate the sound outputted from the array speaker. The number of sound holes is greater than the number of speakers. The array speaker is shielded from the outside by the rest of the speaker cover except for the sound hole.

Abstract: An apparatus for network-coding and a method thereof are provided to increase data transmission capacity by transmitting signals combined with simple calculation. A received signal processor decodes two or more received signals. Two or more decoded received signals are input to a transmitted signal processor(120) from the received signal processor. The transmitted signal processor combines two or more decoded received signals and produces one combined transmitted signal. The transmitted signal processor comprises a combining unit and RSC(Recursive Systematic Convolutional) encoder. Two or more decoded received signals are input to the combining unit(410) from an interleaver. By performing the XOR(Exclusive OR) calculation about the decoded received signal the combining unit produces a combined application signal. The combined application signal is input to the RSC encoder(420). The RSC encoder produces the combined transmitted signal by encoding the combined application signal.

Abstract: A communication opening method in a dual mode portable terminal is provided to open a portable terminal to communication in an integrated method by providing an OTA(Over The Air) opening method using not a short message but a packet data call. A control part in a dual mode portable terminal enters into an OTA opening mode(S201), and reboots the portable terminal(S207). If the portable terminal is turned on again as the rebooting of the portable terminal is completed, the control part displays what the portable terminal has accessed the OTA opening mode(S209). If an input signal for the start of OTA opening is detected(S211), the control part makes a packet data call to a mobile carrier(S213). Also the control part transmits OTA opening information, stored in the portable terminal, to the mobile carrier(S215). Receiving the packet data call, the mobile carrier receives and stores the OTA opening information(S217,S219). The mobile carrier confirms the OTA opening information(S221), and approves OTA communication for the communication modes the portable terminal supports(S223). Then the mobile carrier transmits an OTA opening approval signal to the portable terminal(S225). Receiving the OTA opening approval signal, the control part confirms that OTA opening with the mobile carrier has been completed(S227,S229).

Abstract: A method for exchanging beacons between devices having asymmetric links and a system using the method are provided to classify the devices into a normal power device and a low power device based on a transmission range, so that the low power device can forward beacons to the normal power device through at least one relay device, thereby effectively reducing beacon collision. When a low power device(L) receives beacons of a normal power device(N), the device(L) checks whether an asymmetric link with the device(N) exists on the basis of the received beacons. If so, the device(L) negotiates with at least one relay device(R) to demand relay for the asymmetric link. Based on the negotiated results, the device(R) notifies the device(L) and the device(N) which the device(L) wants to communicate with of the negotiated results.

Abstract: A method for transceiving beacon information in a wireless LAN mesh network is provided to detect or prevent collision between beacon signals by transmitting a periodic probe beacon timing element information in addition to existing beacon timing element information. A receiving MP(Mesh Point) receives beacon timing elements and collects beacon timing information and MAC address information of MPs adjacent to a transmission MP(302). The receiving MP judges whether the first MAC address of a received beacon timing element is identical to the source MAC address(304). In case the first MAC address of the received beacon timing element is identical to the source MAC address, the receiving MP judges whether the self beacon timing information of the received beacon timing element is identical to one among original beacon timing information of neighbor nodes which receiving MP possesses(306). If self beacon timing information of the received beacon timing element is identical to one among original beacon timing information of the neighbor nodes, the receiving MP selects TBBT(Target Beacon Transmission Time) offset as self tentative beacon timing information of the received probe beacon timing element(310). Then, the receiving MP transmits a probe response beacon timing element containing the selected TBBT offset information(312).

Abstract translation: 提供了一种用于在无线LAN网状网络中收发信标信息的方法，用于通过除现有的信标定时单元信息外发送周期性探测信标定时单元信息来检测或防止信标信号之间的冲突。 接收MP（Mesh Point）接收信标定时单元并且收集与发送MP（302）相邻的MP的信标定时信息和MAC地址信息。 接收MP判断接收到的信标定时要素的第一MAC地址是否与源MAC地址相同（304）。 在接收到的信标定时要素的第一MAC地址与源MAC地址相同的情况下，接收MP判断接收的信标定时要素的自身信标定时信息是否与接收到的信标定时要素的邻居节点的原始信标定时信息中的相同 MP拥有（306）。 如果接收到的信标定时要素的自身信标定时信息与相邻节点的原始信标定时信息中的一个相同，则接收MP选择TBBT（目标信标发送时间）偏移量作为接收到的探测信标定时要素的自身信标定时信息 （310）。 然后，接收MP发送包含所选择的TBBT偏移信息的探测响应信标定时元素（312）。
