On decoding algorithms for construction πA lattices
Yu-Chih Huang, Krishna R. Narayanan · 2015
This paper revisits the Construction πAlattices recently proposed by Huang and Narayanan. This lattice construction is a generalization of the famous Construction A to the multilevel coding setting which preserves most of the structures of Construction A. Decoding algorithms of the Construction πAlattices are then studied. Two low complexity decoders are proposed to take advantage of the additional structure of the Construction πAlattices.
