  • Turbo decoder stopping criterion improvement
    Patent number: 6898254
    Abstract: A stopping criterion improvement for a turbo decoder that does not require division by a variable quantity. The stopping criterion improved upon generates a signal-to-noise ratio based on the mean and variance of soft-output estimates. The decoding process is aborted based on a comparison of the generated signal-to-noise ratio to a predetermined threshold.

  • Turbo decoder stopping based on mean and variance of extrinsics
    Patent number: 6879648
    Abstract: An adaptive stopping criterion improvement for an iterative decoder, in which iteration is halted by observing a signal-to-noise ratio generated from the mean and variance of the soft estimates (or their divergence).
