Abstract
In the method, the received spread-coded signal sequence r(i) is first of all correlated with the spread-coded training symbol sequence in a correlator () 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 (). 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 (λ). The sequence of data symbols produced in this way is filtered with fixed or variable filter coefficients in a digital filter () in order to produce channel estimation values ({tilde over (H)}(l)).
