ABSTRACT:
In the method for termination of turbo decoding, a plurality of first LLR values (Lai(k)) of a-priori information and a plurality of second LLR values (Lei(k)) of extrinsic information are called up. A value is determined for a decision variable which is characteristic of the number of mathematical sign discrepancies between the first Lai(k)) and the second Lei(k)) values. The turbo decoding is terminated if the number of mathematical sign discrepancies is less than or at least equal to a first number or if the number is greater than or at least equal to a second number.
