Method for the reception of digital radio signals via radio channels and receiving device for the reception of digital radio signals via radio channels

摘要

It is a method or a receiving device for reception of digital radio signals via radio channels proposed. The or, respectively, which is used for the purpose of the useful data signals corresponding to the transmission characteristics of the radio channel and the speed of the receiving device for equalizing. The estimation of the transfer function of the radio channel is carried out by means of reference signals transmitted. In order to the transfer function of the funkkanls on the user data to transmit signals, interpolation filter for the time - and the frequency range used. These digital filter, as a result of the transfer function of the radio channel, which was determined from the reference signals, from the speed of the receiving device and from the carrier frequency of the signal is determined. With these digital filters is then the determined transfer function for the useful data interpolated signals, in order then to equalize the user data signals.
