Abstract
In a method for demodulation of multistage-modulated data, correspondence variables (decision variables) are determined from the comparison of the received signal with stored signals, and these correspondence variables are converted into a posteriori symbol probabilities. The received signal represents a symbol which in turn represents a data group. The a posteriori symbol probabilities are now accounted for in turn such that one individual probability information item is produced for each bit of a data group, which information indicates the probability of a relevant bit being +1. Reliability values are determined from these bit-specific probabilities, and these reliability values are output, together with the bits, as soft bits.
