PCT No. PCT/DE96/00544 Sec. 371 Date Jan. 30, 1998 Sec. 102(e) Date Jan. 30, 1998 PCT Filed Mar. 29, 1996 PCT Pub. No. WO97/07612 PCT Pub. Date Feb. 27, 1997The method of synchronizing a receiver in a coded data transmission by means of an M-stage channel symbol alphabet, which includes dividing the channel symbol alphabet into a number of K not necessarily equal-sized groups (I,II) with K greater than one, so that at least one group contains less than M channel symbols; and either making preliminary or final data decisions in a data decoder, then making group membership decisions based on the preliminary or final data decisions and continuously using the group membership decisions for selecting a parameter detector (1, 2, . . . , K) or a parameter detector characteristic curve corresponding to an applicable group according to the group membership decisions; or making a group membership decision based on redundancies of received channel symbols present in the coded data transmission and then using the group membership decision for continuously selecting the parameter detector or the parameter detector characteristic curve according to the group membership decision; or determining a probability for group membership in at least one group based on the redundancies of the received channel symbols present in the coded data transmission and then using this probability for selecting weighting factors for output signals of the parameter detector corresponding to the concerned group.
