Cross-packing lattices for the Rician fading channel [PDF]
2015 IEEE Information Theory Workshop (ITW), 2015 We introduce cross-packing lattices for Rician fading channels, motivated by a geometric interpretation stemming from the pairwise error probability analysis. We approximate the star bodies arising from the pairwise error probability analysis with n-dimensional crosses of radius t, consisting of 2nt + 1 unit cubes, for some positive integer t.
