Abstract
A technique of decoding erroneous biphase signals is disclosed comprising the following steps. First, phase and magnitude sample values (ps, bs) are formed, from which a first digital signal (d) is derived. From this, associated bit combinations (StStStp) are determined, and a decision is made as to whether the respective bit combination (StStStp) is a valid combination (SgSgSgp) or an erroneous one (SfSfSfp). Probability values (SwSwSwp) are determined that decide which parts of the erroneous bit combination (SfSfSfp) are probably true and/or which are probably false. Next, a corrected bit combination (SkSkSkp) is formed from the existing information. Finally, a second digital signal (d) is generated as an output signal, whose data states are formed either from the valid bit combination (SgSgSgp) or from the corrected bit combination (SkSkSkp).
