  • By studying the structure of 16 dimension Barnes-Wall lattice and lattices resulting from binary linear block codes and quaternary linear block codes based on Construction A, decoding problem of the lattices can be transformed into the problem of finding the shortest path of trellises accordingly. The time complexities of the decoding algorithms are analyzed.
