Query: Finite-length scaling based on belief propagation for spatially coupled
  LDPC codes   The equivalence of peeling decoding (PD) and Belief Propagation (BP) for
low-density parity-check (LDPC) codes over the binary erasure channel is
analyzed. Modifying the scheduling for PD, it is shown that exactly the same
variable nodes (VNs) are resolved in every iteration than with BP. The decrease
of erased VNs during the decoding process is analyzed instead of resolvable
equations. This quantity can also be derived with density evolution, resulting
in a drastic decrease in complexity. Finally, a scaling law using this quantity
is established for spatially coupled LDPC codes.
