We propose a lattice construction from totally real and complex multiplication fields, which naturally generalizes Construction A of lattices from p -ary codes obtained from the cyclotomic field Q(ζ<inf>p</inf>), p a prime, which in turn contains the so-called Construction A of lattices from binary codes as a particular case. We focus on the maximal totally real subfield Q(ζ<inf>p</inf><sup>-r</sup>)+ζ<inf>p</inf><sup>-r</sup>) of the cyclotomic field Q(ζ<inf>p</inf><sup>r</sup>), ≥ 1. Our construction has applications to coset encoding of algebraic lattice codes for block fading channels, and in particular for block fading wiretap channels.Mahidol UniversityComputer ScienceConstruction a of lattices over number fields and block fading (wiretap) codingArticleSCOPUS10.1109/TIT.2015.2416340
