Constructive Spherical Codes on Layers of Flat Tori

A new class of spherical codes is constructed by selecting a finite subset of flat tori from a foliation of the unit sphere S 2L-1 ⊂ R 2L and designing a structured codebook on each torus layer. The resulting spherical code can be the image of a lattice restricted to a specific box in R L in each la...
