摘要： A wireless content protection system includes a coordinator, a source device, and a sink device. The coordinator includes a scheduler. The source and sink devices each have a content protection manager. One of the content protection manager allocates and releases bandwidth via the coordinator for a test message and a response message for a round-trip time computation. The test message is transmitted in a source-to-sink channel time block. The response message is transmitted in a sink-to-source channel time block. The round-trip time is the period between the end of the source-to-sink channel time block and the beginning of the sink-to-source channel time block.

摘要： A modified branch metric for decoders and equalizers is described. In one embodiment the branch metric includes determining a set of branch metric values for symbols of a received digital signal, the branch metric values indicating a correlation between symbols obtained using a reduced calculation set, the reduced calculation set being obtained by adding a common term to all of the branch metric values before determining the correlation. The branch metric may be followed by determining path metrics for paths through a decision tree using the branch metric values, and selecting a path and a corresponding symbol sequence in the received digital signal using the path metric values.

摘要： Over the air or radiated testing of an RF microelectronic or integrated circuit device under test (DUT) that has an integrated millimeter wave (mmw) antenna structure, is described. The antenna structure may have multiple elements in an array design that may be driven and/or sensed by integrated RF transmitter and/or receiver circuitry. An interface printed wiring board (e.g., a tester load board or a wafer probe card assembly) has formed in it a mmw radiation passage that is positioned to pass mmw radiation to and/or from the integrated antenna of the DUT. Test equipment may be conductively coupled to contact points of the interface board, to transmit and/or receive signals for testing of the DUT and/or provide dc power to the DUT. A test antenna is designed and positioned to receive and/or transmit mmw radiation through the passage, from and/or to the integrated DUT antenna. Other embodiments are also described and claimed.
