    摘要: A method for calculating zero-crossing reference sequences ({ti}) for the data detection of a sequence of zero crossings ({{circumflex over (t)}i}) of a received signal is disclosed. The data detection is determined in a receiver, wherein the received signal is based on a data symbol sequence ({dk}) angle-modulated at a transmitter and transmitted to the receiver. The zero-crossing reference sequences ({ti}) are calculated in accordance with an equation specifying an output of a finite state machine that describes, at least approximately, the signal generation in the transmitter.

    摘要: The invention relates to a radio receiver for receiving received signals transmitted by radio. The radio receiver includes a demodulation unit for demodulating the received signals and a first estimating unit for estimating the noise power of the received signals. The demodulation unit outputs the demodulated received signals as softbits and sets the weighting of the least significant softbit in dependence on the estimated noise power of the received signals.

    摘要: The present invention relates to a transponder reading device for reading out a plurality of inductive passive transponders having a resonant circuit. A transmitter is provided to create an alternating magnetic field having an operating frequency fB, in which the number of transponders may be placed such that same are magnetically coupled to each other. A retuning means is further provided which is arranged in the alternating magnetic field and has such a frequency-dependent impedance that a voltage induced in the resonant circuits of the transponders by the alternating magnetic field has a maximum in the range of the operating frequency fB.
