摘要： The present invention seeks to improve data exchange in a communications system that is especially standardized according to IEEE 802.11a. For this purpose, when the transmission medium, preferably an IEEE 802.11 system with a distributed coordination function (DCF) is accessed in a decentralized manner, pilot signals are transmitted from the transmitter to the recipients using a number of transmission modes and then an allocation table regarding the transmission modes is calculated by the recipient on the basis of the pilot symbols received. The recipient transmits the allocation table to the transmitter so that the subsequent data exchange can proceed on the basis of the allocation table. In the case of centralized access, preferably an IEEE 802.11 system with a point coordination function (PCF), data exchange is improved in that the subsequent data are adaptively modulated already when the allocation table is transmitted.

摘要： A method and OFDM receiver are provided for reducing the influence of harmonic interference on OFDM transmission systems, wherein high interference unity is achieved by the simultaneous use of a window function and a determined item of reliability information, the window function being a Nyquist-shaped window function which generates low side lobes in the subcarrier and interference spectra while simultaneously leaving the orthogonality of the subcarriers unchanged, the determined item of reliability information being derived from a measurement when transmitting a so-called zero symbol, in order to detect the instantaneously active interference signals, with the high interference immunity being achieved when the subcarrier-specific information is taken into account in a so-called Viterbi decoder.

摘要： A method is provided for the adaptive pre-distortion of digital raw data values for a communication appliance output stage having a power amplifier, the method including the following steps: a) the raw data values (Vm) are pre-distorted by multiplying the raw data values by pre-distortion values from a lookup table (2) containing an association between amplitudes of the raw data values and pre-distortion values; b) output signal values (Vr) of the power amplifier (6) are redirected to an adaptation unit (9); d) temporally corresponding raw data values and output signal values are compared in the adaptation unit in order to assess the distortions of the power amplifier (6); and e) the lookup table (2) is adapted on the basis of results of step d). The present invention seeks to dispense with computing power required to adapt pre-distortion values. To this end, the adaptation unit (9) functions discontinuously and the pre-distortion values of the lookup table (2) are interpolated/extrapolated at least for non-occurring raw data values (Vm). A device is also provided for carrying out the inventive method.

摘要： In order to record and to process audio signals with a good useful-signal to noise-signal ratio in acoustic noise conditions and with a good ratio between the direct sound and the reflected sound in an environment which in particular has no reverberation electrical signals produced by conversion of audio signals recorded by a predetermined microphone arrangement are processed in such a manner that, if the sound pressure levels at the microphones in the microphone arrangement are the same, electrical signals which are produced by these microphones but are of different intensity—different sensitivities of the microphones—are automatically matched, without any manual matching procedures needed to be carried out individually and separately. A microphone arrangement is based on combining the characteristics of an array of microphones with those of a method for matching the sensitivity of microphones.
