摘要: 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 processing. This is achieved by adjusting extrinsic information produced a process where magnitude of reduced, for example, multiplying it scale factor between 0 and 1.
