Abstract: A control device includes an acquiring unit and a processing unit. The acquiring unit acquires a voltage course and a current course of a determinable number of periods of a frequency generator and transmits these to the processing unit. The processing unit determines a temporal offset ?t1 between a rising edge of the current course and a rising edge of the voltage course for each period of the determinable number of periods, and further determines if this temporal offset ?t1 is positive or negative. The processing unit determines a difference between the number of periods with positive temporal offset and the number of periods with negative temporal offset within the determinable number of periods, and generates and adapts a switching signal for a switch-on time of the voltage course if the number of periods with positive temporal offset differs from the number of periods with negative temporal offset.

Abstract: Modulator system (1) comprising modulators (2, 3, 4) for modulating input signals (A) according to different modulation schemes (8PSK, GMSK) cause discontinuities in the output signals (F) when switching between the schemes. By providing the modulator systems (1) with compensators (13, 22-26) for compensating amplitudes/phases of the output signals (F) of the modulator system (1) for discontinuities, these discontinuities resulting from modulation scheme changes are reduced to a large extent. This may be done before/after the pulse shapers (11, 21). The compensators (13, 22-26) comprise multipliers for multiplying pulse shaped modulated signals with complex valued waveforms (E), or for multiplying modulated signals with waveforms (S, T), or for multiplying complex valued signals (B, C, D) with complex valued phase offsets (X, Y, Z), which complex valued signals (B, C, D) are to be multiplied with mapped input signals.

Abstract: The present disclosure relates to a method for re-configuration of a hardware peripheral, and a system that includes the hardware peripheral. Processing of large amounts of data in a multifunctional environment in a processor system is enabled in a flexible way by employing a re-configurable and autonomous operating hardware peripheral, which receives and, if necessary, sends data independently of a processor by use of DMA channels. Furthermore, the re-configuration method enables flexible assembling and storing of at least one set of configuration parameters used for the re-configuration of the hardware peripheral. The present disclosure provides the advantage of a flexible and fast way of handling large amounts of temporary data independently of a processor.

Abstract: A transmitter apparatus (1) comprises a digital modulator (2), wherein the modulator is adapted to output a digital in-phase signal and a digital quadrature signal. The digital in-phase signal is converted to an analog in-phase signal and further processed in a path (31) for the in-phase signal, and a digital quadrature signal is converted in an analog quadrature signal and further processed in a path (34) for the quadrature signal. Thereby, an amplitude and delay mismatch in the path can occur. With the transmitter apparatus (1) of the invention the amplitude and delay mismatch can be measured. Further, an amplitude correction unit (43) is adapted for correcting the amplitude mismatch and a delay unit (3) is adapted to correct the delay mismatch. Further refinements of the amplitude and delay mismatch can be made with one or more predetermined test signals generated by a test signal generating unit (30).

Abstract: In a transmitting/receiving concept a redundancy-adding encoder is used in order to obtain two data streams for different transmitters. In the receiver, the receiving signal is sampled by a first sampler synchronous to the first transmitter and is output by a second sampler synchronous to the second transmitter in order to obtain a first and a second receiving signal which are fed to a trellis decoder to obtain a decoded first and second receiving subgroup of code units which are again fed to a calculating means in order to calculate the interference signals which are then combined with the corresponding receiving signals for an interference reduction. The iterative concept enables an interference reduction for receiving signal generated by two spatially separated transmitters. The receiver concept shows a quick convergence and thus enables the two transmitters to transmit in the same frequency band.

Abstract: In a transmitting/receiving concept a redundancy-adding encoder with a code rate larger or equal 0.5 is used in order to obtain two data streams for two different transmitters which are arranged at spatially different positions. Both transmitters transmit in the same frequency band. In the receiver, the receiving signal is sampled by a first sampler synchronous to the first transmitter and is output by a second sampler synchronous to the second transmitter in order to obtain a first and a second receiving signal which are fed to a trellis decoder in order to obtain a decoded first and second receiving subgroup of code units which are again fed to a calculating means in order to calculate the interference signals which are then combined with the corresponding receiving signals for an interference reduction. The iterative concept enables an interference reduction for receiving signal generated by two spatially separated transmitters which are transmitting in the same frequency band, however.
