Abstract:
Transmission system comprisinga transmitter for transmitting digital symbols via a transmission medium to a receiver,said receiver being provided with a decoder for deriving decoded symbols from an input signal of the receiver having a predetermined signal property out of a plurality of possible signal properties,said receiver comprising property determining means for determining said predetermined signal property from the received signal by determining the reliability of the decoded symbols,the property determining means further being arranged for deriving at leasta first sequence of decoded digital symbols assuming a first signal property anda second sequence of decoded digital symbols assuming a second signal property,characterized in that the property determining means are arranged for indicating the signal property corresponding to the sequence of decoded symbols having the highest reliability as the correct signal property if a normalized difference measure of the reliability measures of the first and second sequence of decoded symbols exceeds a predetermined value.
