Abstract
The invention comprises an enhancement to max-log-APP processing that significantly reduces performance degradation associated with introducing the "max" approximation into log-APP computations, while still maintaining lower computational complexity associated with max-log-APP processing. This enhancement is achieved by adjusting extrinsic information produced by a max-log-APP process where the magnitude of the extrinsic information is reduced, for example, by multiplying it with a scale factor between 0 and 1.
