Abstract :
For a given family of spatially coupled codes, we prove that the LP threshold on the BSC of the tail-biting graph cover ensemble is the same as the LP threshold on the BSC of the derived spatially coupled ensemble. This result is in contrast with the fact that the BP threshold of the derived spatially coupled ensemble is believed to be larger than the BP threshold of the tail-biting graph cover ensemble [1], [2].
