Spatially-coupled low-density lattice codes
(LDLC) are constructed using protographs.
Using Monte Carlo density evolution using single-Gaussian messages,
we observe that the threshold of the spatially-coupled LDLC
is within 0.22 dB of capacity of the unconstrained power channel.
This is in contrast with a 0.5 dB noise threshold for the conventional LDLC lattice construction. |
