Abstract: 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.

Abstract: A multiplication or division operation X·K or X·1/K is performed in an electronic circuit. A software circuit area of the circuit calculates a digit shift sv such that psv is an approximate value for K. In a hardware circuit area, the value X is shifted sv digits to the left in the case of multiplication or sv digits to the right in the case of division. The software circuit area calculates a suitable correction factor Kf. The value X is multiplied by the correction factor Kf.

Abstract: In the method, the received spread-coded signal sequence rk(i) is first of all correlated with the spread-coded training symbol sequence in a correlator (24) so as to counteract the influence of the transmitted training symbols. The signal sequence which results from the correlation process is then despread in a despreading apparatus (21, 22). The despread signal sequence is integrated over a number (N_MF) of signal values, with the number (N_MF) being set as a function of the channel dynamic range (?). The sequence of data symbols produced in this way is filtered with fixed or variable filter coefficients in a digital filter (25) in order to produce channel estimation values ({tilde over (H)}(l)).

Abstract: In a method for efficient evaluation of measurement values from a bit error rate measurement for indication of channel quality, the characteristic of the transmission channel, and the bit error rate which is dependent on it, are taken into account via their stochastic distribution. This results in the bit error rate being quantized in a form matched to the channel transmission, for indication of the channel quality. Furthermore, the evaluation can be extended by taking account of a weighting function which allows assessment of application-specific requirements.
