TI  - Threshold Computation for Spatially Coupled Turbo-Like Codes on the AWGN Channel.

AB  - In this paper, we perform a belief propagation (BP) decoding threshold analysis 
      of spatially coupled (SC) turbo-like codes (TCs) (SC-TCs) on the additive white 
      Gaussian noise (AWGN) channel. We review Monte-Carlo density evolution (MC-DE) 
      and efficient prediction methods, which determine the BP thresholds of SC-TCs 
      over the AWGN channel. We demonstrate that instead of performing time-consuming 
      MC-DE computations, the BP threshold of SC-TCs over the AWGN channel can be 
      predicted very efficiently from their binary erasure channel (BEC) thresholds. 
      From threshold results, we conjecture that the similarity of MC-DE and predicted 
      thresholds is related to the threshold saturation capability as well as 
      capacity-approaching maximum a posteriori (MAP) performance of an SC-TC ensemble.
