Abstract:
1. A method for generating 1T path equivalency information in a soft output Viterbi algorithm (SOVA) decoder configured for use with an nT clock signal where n is greater than 1, the method comprising: responsive to each nT clock pulse, performing the steps of: applying decision data from an add, compare, select (ACS) component of the SOVA decoder to n path equivalency detector (PED) components of the SOVA decoder; generating path equivalency information from each of the n PED components wherein each of the n PED components generates a corresponding one of 1T path equivalency information through nT path equivalency information; and utilizing the path equivalency information from each of the n PED components to generate soft output information associated with the decision data output of the SOVA decoder.
