    Patent number: 8494533
    Abstract: The present disclosure relates to providing a method of improving data rates in a heterogeneous network which is composed of macro cells and pico cells. User equipment is connected to the network via a macro base station serving a macro cell or a low power node serving a pico cell. A signal strength indicator is received from one or more UEs located in a macro cell and adjacent one or more pico cell. The location of a UE within a region of a macro cell or a pico cell is identified according to the signal strength indicator. Then, a weak coverage area of macro cell is identified according to the signal strength indicator and a beam forming antenna of a macro base station serving the macro cell where the UE is located, is directed to steer the antenna beam to an area of the cell requiring an improved signal strength indicator.

  • Method and arrangement for providing telecommunication services
    Patent number: 8494483
    Abstract: A method and arrangement for providing telecommunication services for subscribers of multiple different operators, using a single communication network controlled by an operator-independent network supervisor. Resources in said network for technically providing telecommunication services can be hired by said operators for serving their subscribers. The operators are then charged for consumed network resources, preferably on the basis of communicated data amounts, used bandwidth, and/or connection time. In this way, only one communication network is needed for offering services from multiple operators in a certain region, and unnecessary duplication of network resources can be avoided.

  • Method and arrangement for locating services in a peer-to-peer network
    Patent number: 8495130
    Abstract: The present invention relates to methods and arrangements for locating services in a structured peer-to-peer distributed hash table, DHT, based, overlay communication network (310). The invention comprises two inter-related methods and nodes. The first method is used by a service node (321) to “advertise” to the overlay network (310) that it is providing a particular service (S1). This is done by distributing instances (351,352,353) of a service object (O1) that are stored in different nodes (331,332,333) in the overlay network (310) and where the instances (351,352,353) comprise an address to the service node (321). The other method is to locate at least one of these instances (351,352,353) with a predetermined probability and with a predetermined number of location request messages (390) from a user node (311) wishing to use the particular service (S1).

  • Method and device for mitigation of multi-user interference in code division multiple access
    Patent number: 8493953
    Abstract: A method and apparatus for mitigating multi-user interference in reception of a code division multiple access (CDMA) signal is described. The CDMA signal has a plurality of spread user symbol streams, each spread by a corresponding one of a plurality of spreading codes. Estimated symbols are iteratively improved by forming a reconstructed signal from the estimated symbols, subtracting the reconstructed signal from the CDMA signal to create a difference signal, and adjusting the estimated symbols based on a combination of the difference signal and the estimated symbols.

  • Digital-to-analog converter image suppression with hilbert transform
    Patent number: 8493258
    Abstract: A method and apparatus for suppressing a first replica of an image spectra and reinforcing a second replica of the image spectra are disclosed. A Hilbert transformer is applied to a first digital signal in a first path. The Hilbert-transformed signal in the first path is converted to an analog signal in the first path. The analog signal in the first path is delayed by an additional 90 degrees to produce a first phase-shifted analog signal. A phase delay is applied to the first digital signal in the second path and the phase-delayed signal in the second path is converted to analog to produce a second phase-shifted analog signal. A combiner combines the first and second phase-delayed analog signals to produce an analog output signal with at least one replica of the image spectra that is substantially suppressed.

  • Identification reader
    Patent number: 8493630
    Abstract: A passport and identification card reader minimizes the time and effort required for an operator to read/scan a passport or piece of identification. An immigration official, for example, can slide a passport into place with one hand while tending to other important security activities with the other hand. Once in place, the passport will be automatically detected and read. Numerous passports bound together by a traveler with multiple visas can be held flat in place and accurately read, even with one hand, despite the natural tendency of the passport(s) to return to a closed position.
