A device for carrying out search procedures includes a memory for storing a digital received data sequence, and a memory storing a predetermined correlation data sequence. A correlation device has a first section, in which sequence elements of the received data sequence are correlated with sequence elements of the correlation data sequence. A variable number K of sequence element correlation results are summed in the second section, in order to form an accumulated correlation result.

Convolutional codes are decoded by calculating, for uncoded and coded symbols, a first and/or second item of reliability information (&Lgr; and &Lgr; respectively). The item of reliability information is representative of the probability that the considered n uncoded or coded symbol is equal to a value i of the symbol set, under the condition that a specific sequence of received coded symbols is present. An approximate expression is proposed for calculating the second item of reliability information.
