    摘要： A software-defined radio includes a communications security processor (221) configured to transmit and receive a plurality of waveforms under a plurality of communications standards, and a reconfigurable resource configured to execute a plurality of software programs. Each of the software programs is capable of reconfiguring the reconfigurable resource to emulate one of a plurality of processors to process a portion of the plurality of waveforms under one of the plurality of communications standards. The reconfigurable resource is implemented on a single chip. In one embodiment, the reconfigurable resource is a field programmable gate array (301). In the same or another embodiment, at least one of the plurality of processors is a digital signal processor (400, 500, 700, 1000).

    摘要： Systems and methods for generating an optimal allocation of marketing investment for a marketing budget based on a marketing variable without requiring historical time-series data or survey data are disclosed. A first advertising elasticity is determined for the marketing variable based on a meta-analysis of a normative database. A second advertising elasticity is determined based on financial data for the offering being analyzed. The first and second advertising elasticities are combined to determine the optimal allocation.

    摘要： A voltage-controlled oscillator in which a tunable resonator (102) having a first port (132) and a second port (106) is disclosed. In one embodiment, the tunable resonator is a series resonating circuit having low driving and load impedances. A power gain element (108) is coupled to the first port and the second port, and an output port (110) is coupled to the power gain element and the second port. The first impedance at the first and second ports is less than approximately ten ohms. The voltage-controlled oscillator is capable of generating a signal at the output port of greater than approximately half a watt.

    摘要： A method and system for detecting GPS interference is disclosed. In one exemplary embodiment, a method for detecting interference in a Global Positioning System comprises the steps of receiving at least one satellite signal from one or more satellites in a Global Positioning System; identifying a noise floor value from the at least one satellite signal; identifying an interference signal based on the noise floor value; determining an interference value for the interference signal from the noise floor value wherein a level of the noise floor value corresponds to a level of interference; and providing the interference value to at least one user for informing the user of the interference signal.
