摘要： A built-in receiver self-test system provides on-chip testing with minimal change to the receiver footprint. The system digitally generates a two-tone test signal, and tests the nonlinearities of the receiver using the generated two-tone test signal. To that end, the self-test system comprises a stimulus generator, a downconverter, and a demodulator, all of which are disposed on a common receiver chip. The stimulus generator generates a test signal comprising first and second tones at respective first and second frequencies, where the first and second frequencies are spaced by an offset frequency, and where the first frequency comprises a non-integer multiple of the offset frequency. The downcoverter downconverts the test signal to generate an In-phase component and a Quadrature component. The demodulator measures an amplitude of the intermodulation tone by demodulating the In-phase and Quadrature components based on a reference frequency.

摘要： The invention relates to a method and a device for measuring the antenna diversity gain in digital radio transmission systems, wherein the sensitivity of a receiver system is designed by using a plurality of antennas, wherein the signals thereof determine a diversity gain (DG) by means of the bit error rate (BER)- increase of the signals. The invention is characterized in that the method and the device for measuring the diversity-gain (DG) in digital radio transmission systems form an optimization of radio net planning by means of targeted use of diversity, wherein a decrease of the number of used base stations and an increase of the transmission- and receiving quality is achieved.

摘要： The present invention describes a new distributed decision making scheme for adaptive signal detection. The innovation describes an adaptive system and method for allocating signal detection resources that are used to find out the status of channel use (occupied/unoccupied). The system includes selection of suitable spectrum sensing methods and decision combining techniques as well as the associated parameters to meet the requirements set for the system in the specific operational environment. The result is that the system has good performance, simple implementation and is applicable to versatile time-variant situations.

摘要： A method and apparatus for providing an oscillating signal within a transmitter/receiver circuit is described. The transmitter/receiver circuit may include an oscillator that generates an oscillating signal that may be provided to a low power, low gain mixer of the transmitter/receiver circuit along a shorter circuit path that includes low power circuitry, such as low power buffers and low power frequency dividers. The oscillating signal may also be provided to a high power, high gain mixer along a longer circuit path that includes high power circuitry, such as high power buffers and high power frequency dividers. Specifically, the low power circuitry is adapted to consume less power in an ON state than the high power circuitry in an ON state, and the shorter circuit path has a shorter electrical path length than the longer circuit path.
