Abstract
A technique of decoding a biphase signal comprises sampling the biphase signal to obtain phase sample values and sampling the biphase signal to obtain magnitude sample values. A first digital signal is derived from the phase sample values and associated bit combinations are formed from the first digital signal. A decision is made whether the bit combination is an erroneous bit combination, and a probability check is performed to obtain probability values that decide which parts of the erroneous bit combination are true and which are false. A corrected bit combination is generated from the obtained probability values, and a second digital signal is generated whose data states are formed from the valid bit combination and, in the presence of an erroneous bit combination, from the corrected bit combination.
