    Abstract: A method for identifying keypoints in a digital image including a set of pixels. Each pixel has associated thereto a respective value of an image representative parameter. The method includes approximating a filtered image. The filtered image depends on a filtering parameter and includes for each pixel of the image a filtering function that depends on the filtering parameter to calculate a filtered value of the value of the representative parameter of the pixel. The approximating includes: a) generating a set of base filtered images; each base filtered image is the image filtered with a respective value of the filtering parameter; b) for each pixel of at least a subset of the set of pixels, approximating the filtering function by a respective approximation function based on the base filtered images; the approximation function is a function of the filtering parameter within a predefined range of the filtering parameter.

    Abstract: A method for selecting routing paths of data packets in a data network including plural communication links and routing apparatuses. The method includes: calculating and assigning to the communication links respective communication links' costs; calculating, for at least two different routing paths, respective routing path overall costs, which depend on the communication links' costs assigned to communication links making up such routing path; selecting, among the at least two different routing paths, the routing path having the lower routing path overall cost; causing a new data packet to be routed in the data network over the selected routing path, and collecting measures indicative of at least one performance parameter indicating a performance of previous transmissions of data packets from origin end points of the data network to destination end points of the data network, and using the collected measures for calculating the communication links' costs.

    Abstract: A method for allocating resource blocks on a cellular network including transceiver stations to provide cell coverage for allowing user equipment within the cell to exchange data via uplink or downlink. The method includes, at a cell, reiterating operations at each or a group of transmission time intervals. The operations include listing user equipment requiring resource blocks in a priority list; b) for the user equipment listed in the priority list, executing operations b1) and b2) or b1) and b3): b1) selecting a set of resource blocks including at least one resource block; b2) if the selected set of resource blocks has not been assigned to other user equipment, assigning to the user equipment the selected set of resource blocks; b3) if the selected set of resource blocks has been assigned to other user equipment, replacing the user equipment from the priority list with user equipment in a collision list.

    Abstract: A method for uplink allocation of radio resources in a cellular network including a network node and, associated therewith, at least one user equipment supporting data reception from a global navigation satellite system. The method includes, for each of the at least one user equipment: if uplink data transmission from the user equipment to the network node is based on aggregation of carriers and if data reception from the global navigation satellite system is enabled, determining a reception time interval, with respect to a framing system of the cellular network, during which data reception from the global navigation satellite system takes place, the determining based on timing information concerning data reception by the user equipment from the global navigation satellite system; if uplink data transmission potentially takes place at least partially within the reception time interval, limiting allocation of radio resources for the uplink data transmission from the user equipment.

    Abstract: An iterative receiver is proposed for receiving in a cell a signal and for providing information carried on the signal by execution of at least one processing iteration. The receiver includes an estimate assembly for receiving the signal and providing, at each one of the processing iterations, a respective information estimate; a regeneration assembly for receiving, at each processing iteration, the information estimate provided by the estimate assembly at that iteration, and for providing a regenerated signal therefrom based on the information estimate and on attenuation of radio channels over which the signal has been transmitted; an interference estimate unit for providing, at each iteration, an interference estimate based on the signal and the regenerated signal, the estimate assembly providing, starting from a second processing iteration of the processing iterations, the information estimate based on the interference estimate; and an extraction unit for extracting the information from the information estimate.
