METHOD FOR DETERMINING CHANNEL COEFFICIENTS OF A DATA TRANSFER CHANNEL WITH A VARIABLE NUMBER OF COEFFICIENTS

摘要

The invention relates to a method for determining channel coefficients (fj) of a data transfer channel for the correction of transfer modifications according to the transfer of data via the data transfer channel. A transmitting bit sequence (sI) is provided as a receiving bit sequence (eI) after the transfer thereof via the data transfer channel and the transmitting bit sequence (si) has a predetermined channel estimation bit sequence (vi) for the determination of the channel coefficients, and also for the determination of channel coefficients (fj) from the receiving bit sequence (ei) and the channel estimation bit sequence (vi). First channel coefficients (hj) are determined by using a maximum channel length (L) (116, 216) and second channel coefficients (gj) are determined by using a reduced channel length (L*) (118, 224) and the channel coefficients (fj) are selected from the first channel coefficients (hj) or from the second channel coefficients (gj) (130, 226).
