Abstract
In a mobile radio system including mobile terminals each terminal comprises, on the receiving side, a unit using the Viterbi algorithm for equalization or for decoding the received signals after demodulation. A decision device of this system calculates the mean and the standard deviation of the metrics of each branch of the Viterbi algorithm, determines a quality level of a transmission parameter corresponding to the results of this calculation and compares the estimated quality level and a required quality level of the parameter in order to produce a decision signal supplied to a decision unit which can modify one or more transmission characteristics.
