  • Synthesis of authenticable luminescent color halftone images
    Publication number: 20120043751
    Abstract: The present invention enables creating authenticable multi-ink luminescent continuous tone color halftone images offering means of verifying their authenticity. The invented luminescent color halftone image synthesizing techniques enable increasing the attractiveness and aesthetics of color images. The invention relies on daylight luminescent inks, color prediction models for daylight luminescent halftones, color gamuts of luminescent and non-luminescent inks, color separation into luminescent and non-luminescent ink layers, mapping of input gamuts into a luminescent target gamuts by gamut reduction and/or expansion strategies, and luminescent color halftone image generation. The basic authentication is performed by examining the excitation trace image of the synthesized luminescent color halftone image under an illuminant active within its excitation wavelength range.

  • Adaptation of Receiver Settings in a Heterogeneous Network
    Publication number: 20120044818
    Abstract: Techniques are described for adapting receiver settings used by a mobile terminal operating in a heterogeneous network comprising macro cells and pico cells with overlapping coverage areas. A first set of subframes is allocated to the pico cells for downlink transmissions to a mobile terminal in a link imbalance zone. The mobile terminal acquires information about the subframe allocation and uses the subframe allocation information to select the signals used for adapting receiver settings used when operating in the link imbalance zone.

  • Methods and Devices for Point to Multipoint Traffic Path Encoding
    Publication number: 20120044936
    Abstract: The present invention relates to network nodes and methods that use an encoding scheme for encoding a point-to-multipoint traffic path from one ingress node to a plurality of egress nodes in, for example, a Multi-Protocol Label Switching network. According to the encoding scheme a so-called common ERO is used. The common ERO specifies a list consisting of nodes that are common to several sub paths in order to provide a compression mechanism that reduces the size of path messages that are used for signaling the point-to-multipoint traffic path.

  • Estimating the angle of arrival of a signal received by an array of commutated antenna elements
    Patent number: 8121225
    Abstract: The angle of arrival is estimated for a received signal received by an array of commutated antenna elements, wherein there is a temporal boundary at the instant of commutation between antenna elements. Samples of the signal received by the elements of the array are preprocessed to construct maximum-likelihood-estimates of the received signal for points in time that are immediately adjacent the temporal boundaries and thereby provide a preprocessed signal. A maximum-likelihood-estimation of the angle of arrival of the received signal is made for the array of commutated antenna elements by processing the preprocessed signal.

  • Media content management
    Patent number: 8121421
    Abstract: The invention relates to media management and combats media degradations arising when transcoding the media. The invention solves this by—generating processing hints based on the media transcoding. The hints are employed for controlling a post-transcoding processing of the transcoded media content in connection with rendering the media. The hints and this controlled processing increases the user-perceived quality when rendering the media by mitigating the media degradations caused by the transcoding. The processing hints could specify how the actual transcoding was performed by including values of the employed transcoding parameters or information of the alterations to the media caused by transcoding. Furthermore, instructions or commands for appropriate post-transcoding processing could also be processing hints according to the invention.

    Abstract: A method and a device for channel response determination for a wireless communication system. The method comprises generating a first vector of channel responses from channel estimations obtained by using a training signal. A second vector of regularized channel responses is generated by applying to the first vector a regularization algorithm. The algorithm is operative such that a second difference between consecutive regularized channel responses of the second vector is less than a first difference between consecutive channel responses of the first vector.

  • Contention-based random access method with autonomous carrier selection
    Patent number: 8121145
    Abstract: The method and apparatus described herein controls transmission from a plurality of user terminals to an access point on a random access channel in a wireless communication system. An access point determines an allowed information rate for each user terminal and transmits a rate control parameter indicative of the allowed information rates to the user terminals. The access point also computes a packet transmission probability and transmits the packet transmission probability to the use terminals on a common control channel. The packet transmission probability controls the number of user terminals that transmit in a given time slot to reduce collisions and increase the departure rate. The user terminals selectively transmit one or more packets to the access point in a time slot on the random access channel based on the allowed information rate and the packet transmission probability.
