PURPOSE: A VPC(Virtual Private Community) creation method, communication apparatus using the same, and network including herb are provided to create a virtual personalization group by using a personal communication apparatus. CONSTITUTION: One or more communication apparatuses(113, 115, 117) creates hierarchical content name by using a content name and a virtual group identifier which indicates the hierarchical structure of a first and a second VPC transmitted by one or more communication apparatuses. The communication apparatuses are included in the first VPC and the second VPC. One or more herbs(111, 131, 151) processes the content request of the communication apparatuses by using the hierarchical content name.
Abstract:
PURPOSE: Power using a moving body and a data transfer apparatus and a method thereof are provided to secure transfer efficiency, which is changeable due to a distance difference for transmission and reception between a transmitter and a receiver, to be over a constant value using a moving body. CONSTITUTION: A device searcher(110) searches an object device for charging which is distributed in a space through path movement. The device searcher searches the object device for charging using the location information of each device which is placed in the space. A charge determining unit(120) determines whether a searched device is charged or not of if the object device for charging is searched. A power transmission unit(130) transmits power to the searched device. The power transmission unit simultaneously transmits the power to more than two devices.
Abstract:
PURPOSE: A method for encrypting/decrypting data from the terminal of a CDMA(code division multiple access) wireless communication system having data protection function is provided to keep data secret at the other places except both transmitting and receiving terminals by protecting the data with a block cipher or a cipher key. CONSTITUTION: A vocoder packet information bit is generated by coding of an input signal into a specific size of information bit. The coded vocoder packet information bit is block-encrypted. The encrypted vocoder packet information bit is formed as a CDMA frame by combination with a frame quality indicator and encoder tail bits. Finally, the CDMA frame is transmitted to a base station through a frequency band allocated in a process of convolutional encoding, interleaving and band expanding. Therefore, the CDMA frame is kept secret safely during transmitting.
Abstract:
PURPOSE: A mobile communication device having transmission/reception multiple antennas and a method therefor are provided to minimize the influence of interference and noise by minimizing long-term and short-term information and feeding back minimized long-term and short-term information from an MS(Mobile Station) to a base station. CONSTITUTION: A base station(10) having at least one transmission antenna recovers long-term and short-term information and an SINR(Signal to Interference and Noise Ratio) from a received feedback signal, and spatially processes DPCH(Dedicated Physical CHannel) signals, using basis information generated from recovered long-term and short-term information and the recovered SINR. The base station(10) transmits a result, in which the spatially processed result and pilot signals are added, to MSs(20-24). Each of the MSs(20-24) having at least one reception antenna measures the first characteristic corresponding to the characteristic of a transmission and reception antenna classified downlink channel from the pilot signals transmitted from the base station(10). Each of the MSs(20-24) decides downlink power control information including long-term and short-term information and the SINR with reference to the first characteristic, converts decided downlink power control information into the feedback signal, and transmits the feedback signal to the base station(10).
Abstract:
PURPOSE: A synchronization gaining device with respect to asynchronous wideband DS/CDMA(Direct-Sequence/Code Division Multiple Access) receiving signal is provided to determine if the synchronization is gained by differentially coherent combining the ith output with the (I-1)th output of the match filter for the L number of sectors. CONSTITUTION: A long-code masking correlator(500) correlates the control channel signal and the generated common short-code. A differential combiner(502) differentially combines the results of correlation and then determines the gain of synchronization of the slot. A GIC(Group Identification Code) gain unit(504) correlates the GIC and LC masking sector and combines the results of match filtering of one frame or the more times as the positive number to select a GIC of highest output value. The GIC selected is determined to be the code group of the base station where the terminal belongs to and the frame synchronization is gained at the same time. An LG(Long Code) gaining unit(506) match-filters the W number of LC belonging to the code group gained by the GIC gaining unit and the sectors other than the LC making sector to select the LC of the highest value.
