The present invention discloses a predistortion apparatus, a predistortion system and a predistortion method. The predistorter comprises a modular value calculating section, for performing modular arithmetic on an information source input signal inputted from an information source; an orthogonal lookup table value acquiring section, for searching N stored lookup tables orthogonal to one another, finding out corresponding output of each lookup table in accordance with the modular value of the information source input signal, and acquiring N lookup table values, wherein N is an integer greater than 1; a multiplying section, for multiplying the N lookup table values acquired by the orthogonal lookup table value acquiring section with N amplitude adjustment factors to obtain N amplitude adjustment values, and multiplying the N lookup table values with N phase adjustment factors to obtain N phase adjustment values; and a summating section, for summating the N amplitude adjustment values to obtain an amplitude predistortion value, and summating the N phase adjustment values to obtain a phase predistortion value.

In current Distributed Storage Systems, applications may determine the device on which data shall be stored. The invention provides a method for automatically selecting an individual storage device within a DSS. A method for automatically classifying a node in a network comprises determining data classes, automatically classifying data of said data classes stored on a node, determining the amount of stored data per data class, calculating data dominance values for each of the data classes, receiving a request that indicates a data type according to one of said data classes, and providing said dominance value according to the requested data class.Further, a method for automatically organizing nodes in a network comprises receiving a request for storing data of a particular data type, transmitting the request to storage nodes, receiving from the storage nodes respective dominance values, and selecting the node with the highest dominance value for storing the data.

Embodiments of the present invention provide a method and device for interworking between Internet Protocol (IP) networks of. The method includes: judging whether the home network of a called UE supports the IP version of a calling UE, and forwarding a message sent from the calling UE to a home calling state control device of the called UE if yes, otherwise, performing an IP version transformation of the message and sending the message to the home calling state control device of the called UE; judging whether the called UE supports the IP version of the message, forwarding the message to the called UE if yes, otherwise, performing an IP version transformation of the message and sending the message to the called UE. The method and device can reduce unnecessary transformation between different IP versions and improve the interworking between IP networks when the IP Multimedia Subsystem (IMS) is employed.

A logical quality-of-service management method for peer-to-peer networks uses a special group service for QoS management within peer-groups. This group service determines and assigns a budget per time unit for each peer. Such time unit may be in the range of milliseconds or few seconds. It may also determine a group budget for the peer-group. While a peer uses bandwidth, i.e. while it sends or receives data, its budget is decreased. When a peer has exhausted its budget, it has to lower its priority for transferring or receiving data. Each peer is responsible for keeping its own budget. If a peer does not keep the conditions, other peers may have the right to deny the data transfer from that peer. The QoS service function is advertised in peer-group advertisement messages.

A method for changing a route in wireless communication involves: when there is subscriber equipment requesting a change of route in a cell, a base station negotiates downlink measurement contents with a relay station facilitating the route change in the cell; a network side informs the subscriber equipment requesting a change of route of the negotiated downlink measurement contents, and the subscriber equipment executes a downlink measurement according to the received measurement contents and reports the downlink measurement results to a radio access point; and the radio access point executes the route change for said subscriber equipment according to the received measurement results. The method can effectively improve the accuracy of the route change and alleviate the delay due to the route change.

A system and method for virtual canvas generation, product catalog searching, and result presentation. A user that searches multiple virtual catalogs can be provided with search results in a highly useful format. The search results can include a ranked list of product catalogs along with a further display of a non-sequential set of catalog page images that include product information. Virtual canvases can also be created that are customized based on various criteria, such as the characteristics of the user device. The virtual canvas can also include supplemental data that is associated with the search result set.
