    摘要: In one or more embodiments taught herein, a multi-band MIMO repeater is configured to translate normal wireless mobile bands into other frequency bands in the physical layer. An advantageous, multi-hop repeater chain includes two or more such repeaters, for propagating downlink signals from a base station, and for propagating uplink signals to the base station. Each such repeater may use paralleled homodyne structure transceivers for better SNR, spectrum combiners for uplink signal aggregation, spectrum separators for downlink signal de-aggregation, water mark signal inserters for optimization, and, among other things, spectrum analyzers for frequency band selection. In at least one such embodiment, a multi-hop repeater chain is configured for MIMO operation in an LTE Advanced or other MIMO network, to deliver high data rate over larger distances—e.g., further away from cell base stations.

    摘要: In a method of frequency down-converting an input signal to an output signal, a first local oscillator signal is generated as a square wave having a duty cycle of 1/3 or 2/3, and the input signal is mixed with the first oscillator signal to achieve a first down-converted signal, A second local oscillator signal is generated as a modified square wave having the same period time and a duty cycle of 2/3, of which one part has a positive amplitude and another part has a negative amplitude. The input signal is mixed with the second oscillator signal to achieve a second down-converted signal. The first oscillator signal has a delay of 1/4 of the period time to achieve a phase shift of π/2 between the oscillator signals, and at least one down-converted signal is multiplied by a pre-calculated factor. The resulting down-converted signals are added to achieve the output signal.

    摘要: A wireless communication device provides a method of certificate-based access control. Particularly, the device establishes a secure communications session with a device management server. Rather than use access control lists to control access to the functions and services on the device, however, the device uses the certificate that was employed to establish the secure session to control access.

    摘要: A method and a filter element for preventing scraping/clipping of the information content of a database used for providing a website with data information. When a data record set from the database has been received, the filter splits all elements/fields of the data record set in a predetermined way into cells and a sortid is provided. Each cell is encoded into a markup language, wherein location information in the cell is used for generating a location value. The encoded cells are sorted into a file to establish a file, e.g. web page, wherein the encoded data cells are distributed in an arbitrary order.

    摘要: A method and arrangement for providing information to a client (200) from a client access network (202) regarding a requested set of users (204), at least some of which are connected to other access networks (206). In response to a client subscription request, the client access network establishes a network subscription with the other access networks. Information updates regarding users in the set are then continuously received and stored in a database (214) of the client access network, whenever the users change their state. In response to a subsequent request for user information from the client, corresponding stored user information is retrieved from the database and sent in a notification to the client.

    摘要: A first signal representation of one or more of the multiple channels is encoded in a first encoding process, and a second signal representation of one or more of the multiple channels is encoded in a second, filter-based encoding process. Filter smoothing can be used to reduce the effects of coding artifacts. However, conventional filter smoothing generally leads to a rather large performance reduction and is therefore not widely used. It has been recognized that coding artifacts are perceived as more annoying than temporary reduction in stereo width, and that they are especially annoying when the coding filter provides a poor estimate of the target signal; the poorer the estimate, the more disturbing artifacts. Therefore, signal-adaptive filter smoothing is introduced in the second encoding process or a corresponding decoding process.

    摘要: An application is loaded into a device, such as downloading an application into a portable device, such as a mobile telephone, by downloading the application with a signature to the device. The signature of the application is coupled to a predefined attribute certificate stored in the device. The application and said attribute certificate are then installed together. The signature of the application may be coupled to a root certificate that in turn links the application to a predefined attribute certificate.

    摘要: Teachings herein schedule a data transmission in a variable bandwidth wireless communication system based on the power efficiency of a mobile node. One or more processing circuits, of the mobile node or a network node, determine the value of a control setting that defines a power efficiency configuration of the mobile node. In one embodiment, for example, the power efficiency configuration indicates the mobile node is configured to operate at the maximum power efficiency attainable without the data rate of the data transmission falling below a minimum data rate required by a quality of service. Regardless, the one or more processing circuits select from different possible bandwidths of the data transmission a bandwidth that supports a given data rate and that, according to a power efficiency model that models power efficiency of the mobile node for the different possible bandwidths, yields a power efficiency comporting with the power efficiency configuration.
