摘要： In a cascaded sigma-delta modulator, in particular for converting time-discrete samples into corresponding analogue signals in digital radio communication receiving devices, the error signal of a sigma-delta modulator of the cascade being fed to a next sigma-delta modulator of this cascade, the output signal yi−1(k) of the preceding i-1 sigma-delta modulator is also fed to the decision circuit of the ith sigma-delta modulator of the cascade.

摘要： A method, apparatus, and computer program for modeling mathematically an effect of a plurality of factors on signal distortion caused by a non-linear amplifier are provided. First, there is computed a global model which incorporates a combined effect of the plurality of factors on signal distortion caused by the non-linear amplifier. Before applying the pre-distorted transmission signal to the non-linear amplifier, a transmission signal is pre-distorted with coefficients derived from the global model thus compensating for the signal distortion caused by the non-linear amplifier.

摘要： An apparatus produces a reduction signal for a signal having a plurality of subcarriers. The apparatus has a limiter which is designed to produce a limited signal from the signal having a plurality of subcarriers; -a coefficient ascertainment unit which is designed to determine coefficients for unused subcarriers of the signal having a plurality of subcarriers from the limited signal; and -a signal generator which is designed to generate the reduction signal from the coefficients. The reduction signal is able to be combined with the signal in order to form a reduced signal. The coefficient ascertainment unit is designed to project the limited signals onto a K-th base formula.

摘要： A method for influencing the channel separation of an audio signal to be reproduced, obtained from a received radio signal, in a radio receiver, as well as a radio receiver for carrying out the method includes an auxiliary field strength signal derived from the received field strength of the received radio signal, and an auxiliary interference signal derived from signals indicating reception interference events, being combined with one another and with an auxiliary channel separation signal that is derived from a signal indicating the frequency of interference events, to yield a factor D which influences the stereo channel separation.
