Abstract

A method for estimating channel parameters of radio channels of a W-CDMA mobile radio system, for example in accordance with the UMTS standard includes transmitting sequences of known symbols between unknown data symbols by a base station. The channel estimation is carried out by a comparison of the received sequences with the known symbols, and the result of the comparison is integrated over a sequence of known symbols.
