Rate-Equivocation Optimal Spatially Coupled LDPC Codes for the BEC Wiretap Channel

Vishwambhar Rathi, Ruediger Urbanke, Mattias Andersson +1

We consider transmission over a wiretap channel where both the main channel and the wiretapper's channel are Binary Erasure Channels (BEC). We use convolutional LDPC ensembles base…
