Abstract
A method for estimating a channel impulse response of a mobile radio channel is described. The mobile radio channel is accessed over a wide bandwidth by a code division multiplex method. A second mobile radio channel continuously transmits sequences to a multiplicity of mobile radio receivers, and the sequences are known to each of the multiplicity of mobile radio receivers. The delay parameters of the mobile radio channel are estimated using the sequences transmitted via the second mobile radio channel. The mobile radio receiver is adjusted in accordance with the delay parameters estimated and weighting factors of the mobile radio channel are determined.
