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…
Performance Analysis and Design of Two Edge Type LDPC Codes for the BEC Wiretap Channel
Vishwambhar Rathi, Mattias Andersson, Ragnar Thobaben +2
We consider transmission over a wiretap channel where both the main channel and the wiretapper's channel are Binary Erasure Channels (BEC). We propose a code construction method us…
Nested Polar Codes for Wiretap and Relay Channels
Mattias Andersson, Vishwambhar Rathi, Ragnar Thobaben +2
We show that polar codes asymptotically achieve the whole capacity-equivocation region for the wiretap channel when the wiretapper's channel is degraded with respect to the main ch…
