Abstract
The method of receiving a coded data signal encoded by means of a state transition diagram having a number of states (U, V, W, X) by a receiver, the receiver including a demodulator that generates estimated symbols (c′,) from the data signal and a following data decoder, includes forming a number (N) of groups (a,b) from the states (U, V, W, X) of the state transition diagram; continuously making estimations of probabilities of group membership of a current state of the data decoder (Dd) in the groups (a,b); furnishing the estimations to the demodulator as assisting signals and generating the estimated symbols (c′,) using them. In another embodiment, a number (K) of groups (I,II) are formed from channel symbols of a channel symbol alphabet, estimates of probabilities of group membership of received symbols are continuously made, the estimates are supplied to the demodulator (Dd) as assisting signals and the estimated symbols (c′,) are generated from them.
