Abstract
A method of terminating iteration calculations in the decoding of a received convolutionally coded signal includes a first step of providing a turbo decoder with a first and second recursion processors connected in an iterative loop. Each processor has an associated extrinsic input and output. A next step includes cross-correlating the input and output of at least one of the processors to provide a cross-correlation value at each iteration. A next step includes terminating the iterations when the measure of the cross-correlation value index exceeds a predetermined threshold.
