摘要： An apparatus includes an encryption circuit. The encryption circuit includes a block function circuit to generate a plurality of blocks of output data. A first part of a keystream is generated from a block of output data having an initial sequence number. A second part of the keystream is generated from blocks of output having sequence numbers other than the initial sequence number.

摘要： A system and method for detecting the preamble of a wireless packet is disclosed. The system utilizes one or more received fragments as inputs to a correlator, forming correlator content inside the correlator memory. After every sample from the received fragment is provided to the correlator, the correlator then compares the correlator content to a known pattern pre-programmed as a set of correlation coefficients. The correlation coefficients may not align with the correlator content because the symbol boundaries are not known a-priori. By cyclic rotation of the correlation coefficients relative to the correlator content, or cyclic rotation of the correlator content relative to the known correlation coefficients, a match with one or more preamble symbols may be found. This technique may be used to reduce power during the preamble detection process. Alternatively, this technique can also be used for antenna diversity, multi PHY and multichannel applications.

摘要： A system and method for simplifying the creation of documentation, and especially software documentation. A software application, referred to as a source metadata tagger and document compiler is used to add metadata to a final output document. This metadata contains identifiers that are associated with various source files. In this way, the system can easily determine which source file is being reviewed and/or flagged by the reviewer. This information can be used by the ticketing/notification system to create a work item for the appropriate developer or development group. This is vastly simpler than the current system, where human intervention is required to determine which source file is being flagged.

摘要： Modulation testing separately enables slices of an analog varactor array of an LC oscillator. For each enabled slice, a reference voltage supplying a resistor ladder is set to a plurality of different reference voltage values. Resistor ladder voltages generated for the different reference voltage values are supplied to the enabled slice and a control voltage coupled to the enabled slice is swept for each of the reference voltage values. Respective frequencies of an oscillator signal coupled to an output of the LC oscillator are measured for each enabled slice for each combination of the reference voltage values and the control voltage values. The linearity of LC oscillator gain is determined for each of the reference voltage values for each slice based on the respective frequencies and the control voltage values. Passing/failing the modulation testing is based on the linearity of the LC oscillator gain.

摘要： A bitstream modifier is operative on a packet which uses repetition coding. The bitstream modifier increases randomness of the data in a deterministic manner such that spectral spurs from repetition coding are greatly reduced, thereby providing greater available transmit power. In another example of the invention, baseband samples of a header and/or payload for a Bluetooth packet are modified by a canonical sequence with a low slew rate for data such that the variations in frequency may be tracked by a receiver and the transmitted spectral spurs reduced.

摘要： A system that is capable of detecting a Man in the Middle attack is disclosed. The system includes a receive circuit for receiving incoming packets. The system also includes a digitized model of at least part of the receive circuit and optionally part of the transmit circuit. The system compares the output from the digitized model with the output from the read circuit to determine the likelihood of a Man in the Middle Attack. In certain embodiments, the digitized model is a finite impulse response filter with multiple taps. The system correctly identifies Man in the Middle attacks more than 90% of the time when the signal to noise ratio is greater than 20 dB.
