    Abstract: A method and system for demapping a hierarchical signal is disclosed. The method includes receiving a hierarchical signal comprising first and second encoded, modulated signals. A conditional probability relating to the structure of the second encoded, modulated signal is determined. The hierarchical signal is demodulated using the conditional probability to generate a first encoded data stream. The first encoded data stream is decoded to recover information bits.

    Abstract: In a voltage converter, a mode configuration is selected in response to a mode control signal using a switch matrix having two or more mode configurations. Each mode configuration corresponds to one of two or more output signal voltages. The output signal is compared with a reference signal to produce a direction comparison signal. The direction comparison signal is used to produce the mode control signal.

    Abstract: Embodiments of systems and methods for efficient broadcasting via random linear packet combining are described. A method for random linear packet combining includes receiving a plurality of data packets from a data source. Additionally, the method may include dividing the plurality of data packets into a plurality of data blocks, and multiplying bits associated with the plurality of data blocks by a set of coefficients to generate a plurality of product values. The method may also include generating an encoded data packet having a plurality of encoded data blocks, wherein generating the encoded data packet comprises linearly combining the plurality of product values for respective data blocks of each of the plurality of data packets into corresponding encoded data blocks of the encoded data packet. Because each encoded data packet includes information about a complete set of data packets, rather than just a subset, less broadcast redundancy may be required.

    Abstract: Systems and methods which provide data communication content delivery through a hybrid network implementation are disclosed. A hybrid network configuration may utilize a broadcast communication technique to deliver large amounts of data communication content to one or more mobile communication device via uni-directional network links and a uni-cast communication technique via bi-directional network links with the one or more mobile communication device to facilitate delivery and utilization of the data communication content. Data content delivery loss recovery techniques implemented according to embodiments of the invention utilize network links of the hybrid network other than or in addition to the uni-directional network links to implement loss recovery techniques such as a hybrid repeat technique, a hybrid retransmission technique, hybrid statistical feedback technique, and/or combinations thereof.

    Abstract: In one embodiment, differential signaling and ground contacts are located in a rectilinear array of rows and columns with ground contacts spaced apart by three times the pitch distance between adjacent rows or columns and signaling contacts are located immediately adjacent the ground contacts. In particular, the two contacts of each differential pair are located one pitch distance apart from each other and one contact of each differential pair of contacts is located one pitch distance from a ground contact and the other contact of the differential pair is located approximately sqrt(2)*pitch distance from the same ground contact. In a second embodiment, differential signaling and ground contacts are located in a hexagonal array with ground contacts located three times the pitch distance between adjacent contacts and signaling contacts located immediately adjacent the ground contacts. In particular, the two contacts of each differential pair are located one pitch distance apart from each other and both contacts of each differential pair of contacts are located one pitch distance from a ground contact.
