Spatially Coupled LDPC Codes Affected by a Single Random Burst of Erasures
Spatially-Coupled LDPC (SC-LDPC) ensembles achieve the capacity of binary
memoryless channels (BMS), asymptotically, under belief-propagation (BP)
decoding. In this paper, we study the BP decoding of these code ensembles over
a BMS channel and in the presence of a single random burst of erasures. We show
that in the limit of code length, codewords can be recovered successfully if
the length of the burst is smaller than some maximum recoverable burst length.
We observe that the maximum recoverable burst length is practically the same if
the transmission takes place over binary erasure channel or over binary
additive white Gaussian channel with the same capacity. Analyzing the stopping
sets, we also estimate the decoding failure probability (the error floor) when
the code length is finite.Comment: Accepted for presentation in 2016 International Symposium on Turbo
