  • Patent number: 8046657
    Abstract: According to a method and apparatus taught herein, a decoding circuit and method decode linear block codes based on determining joint probabilities for one or more related subsets of bits in received data blocks. The use of joint probabilities enables faster and more reliable determination of received bits, meaning that, for example, joint probability decoding requires fewer decoding iterations than a comparable decoding process based on single-bit probabilities. As a non-limiting example, the decoding circuit and method taught herein provide advantageous operation with Low Density Parity Check (LDPC) codes, and can be incorporated in a variety of communication systems and devices, such as those associated with wireless communication networks.

  • Publication number: 20100115588
    Abstract: The present invent ion relates to a mobile advertisement system (100), a method and an application server (40) used to prevent user equipments (10) hosting a forged client 5 application or client software to get access and to hold an external data network connection. According to the present invention, an application server (40) is adapted to receive from the core network (20) of the advertisement system (100) a message comprising an end user identification number (e.g. MSISDN). The application server is further configured to trigger an advertisement confirmation timer which expects to receive an advertisement display confirmation message from the client of the user equipment (10). Upon the timer expiring, the application server (40) request the core network (20) to disconnect the user equipment thereby preventing the user equipment hosting a forged client application to get access and to hold a external data network connection.
