Threshold Improvement of Low-Density Lattice Codes via Spatial Coupling
Low-Density Lattice Codes Spatial Coupling Information Theory
2011/9/20
Abstract: 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...
Achieving a vanishing SNR-gap to exact lattice decoding at a subexponential complexity
SNR-gap subexponential complexity Information Theory
2011/9/15
Abstract: The work identifies the first lattice decoding solution that achieves, in the general outage-limited MIMO setting and in the high-rate and high-SNR limit, both a vanishing gap to the error-p...
