Patent ID: 6888877

Claim:
CDMA receiver for receiving a CDMA signal, which is transmitted at a chip clock rate from a transmitter via various signal paths of a physical transmission channel, in a multi-subscriber environment having: (a) a receiving device for receiving the CDMA signal; (b) a Rake receiving circuit having a number of parallel-connected delay devices for detection of signal components of the CDMA signal which are transmitted via the various signal paths; (c) a channel estimation circuit for estimating channel coefficients h of a transmission channel H by means of a predetermined reference data sequence which is contained in the received CDMA signal; (d) a weighting coefficient calculation device for calculating weighting coefficients m for the various signal components of the CDMA signal as a function of the estimated channel coefficients h and of stored spreading and scrambling codes; (e) a weighting circuit for weighting the signal components with the calculated weighting coefficients m; and having (f) a combiner for combining the weighted signal components to form an estimated received data signal.
