摘要： A baseband processing technique is described that permits to process in an analog signal domain a complex-valued baseband signal to laterally remove interference components resulting, for example, from in-band blocking signals. In an exemplary device implementation, the baseband processing device is configured to receive a baseband signal having a designated signal bandwidth defined by two opposite band edges, wherein a first frequency shift in a first direction toward a first band edge is impressed on the baseband signal. The device comprises a first filter stage adapted to filter the baseband signal exhibiting the first f requency shift to remove interference components behind the first band edge, a frequency shifter stage adapted to shift the filtered baseband signal by a second frequency shift in a second direction opposite the first direction towards a second band edge, and a second filter stage adapted to filter the baseband signal exhibiting the second frequency shift to remove interference components behind the second band edge.

摘要： In up-to date communication devices an intermediate frequency signal is generated at first in a digital way and than is converted to an analogue signal by a digital-to-analogue converter (10). In order to offer a greater flexibility in choosing a particular digital-to-analogue converter (10) the invention proposes to use sigma-delta modulators (8), the output bit width (n) of which is arranged to be configurable. The advantage of providing sigma-delta modulators with a configurable output bit width is that by this the output bit width of the interpolation filters can be easily adapted to the input bit width of a choosen digital-to-analogue converter without the need to change the internal design of a baseband processing circuit.

摘要： In an electro-acoustic transducer, particularly a hydrophone, with a piezoelectric ceramic tube which carries electrodes on its inner cylinder wall, with a holder which seals the face of the ceramic tube, and with a cast-around plastic sheath which hermetically seals the ceramic tube and the holder, to increase the working life of the transducer an access opening to the inside of the ceramic tube through the plastic sheath and the holder is provided, and can be sealed tight by a closure element. After the closure element has been removed, the inner space of the ceramic tube can be rinsed with a drying agent, so that the insulation resistance of the transducer, which is reduced over time by water vapour diffusion, is brought back to the original value. The transducer is thus regenerated, and completely functional again.

摘要： A technique for cell signature determination in a cellular communication network is provided. A method implementation of this technique comprises the steps of providing a set of hypothesis signals, each hypothesis signal including a signature hypothesis, receiving a composite signal including a first signal portion carrying a first signature from a first cell and a second signal portion carrying a second signature from a second cell, wherein the first signal portion and the second signal portion overlap at least partially in time, and obtaining a correlation result by correlating the composite signal with each hypothesis signal. After the first signature has been determined, a set of phantom signatures associated with the first signature is provided. The phantom signatures represent artifacts from the first signal portion in the correlation result. Finally, the second signature is determined based on the correlation result taking into account the set of phantom signatures associated with the first signature.
