Abstract

We propose linear-time encoding and decoding al- gorithms for multilevel LDPC lattices based on Construction D 0 . Moreover, a generalization of Construction D 0 is proposed which leads to a new class of multilevel lattices. Based on this construction, two-level LDPC lattices are designed that achieve performance comparable to that of polar lattices in the power- unconstrained AWGN channel.
