Efficient termination of spatially-coupled codes [PDF]

open access: yes2012 IEEE Information Theory Workshop, 2012
Spatially-coupled low-density parity-check codes attract much attention due to their capacity-achieving performance and a memory-efficient sliding-window decoding algorithm. On the other hand, the encoder needs to solve large linear equations to terminate the encoding process. In this paper, we propose modified spatially-coupled codes.
