Lattice Code Design for the Rayleigh Fading Wiretap Channel

Coding for the Gaussian Wiretap Channel can be done with nested lattices. The fine lattice must be designed in the same way as lattices used on the regular Gaussian Channel while the coarse one must be a lattice whose theta series is minimized. We present a criterion of design of both the fine and coarse lattice when used on a Rayleigh fading wiretap channel.
