Abstract:
1. A method of decoding biphase signals, comprising the steps of: in a first step, forming phase sample values and magnitude sample values from the biphase signal or its components; in a second step, deriving a first digital signal from the phase sample values according to a threshold criterion; in a third step, forming associated bit combinations from the first digital signal; in a fourth step, deciding whether each one of the bit combinations is a valid bit combination or an erroneous bit combination; in a fifth step, performing a probability check to obtain probability values that decide which parts of the erroneous bit combination are probably true and which are probably false; in a sixth step, generating a corrected bit combination by means of the probability values; and in a seventh step, forming a second digital signal whose data states are formed either from the valid bit combination or, in the presence of an erroneous bit combination, from the corrected bit combination.
