Spherical code

WebIt follows that for any packing of nonoverlapping spheres of unit diameter, a spherical region of radius less than or equal to τ centered on an arbitrary sphere center cannot enclose a number of sphere centers greater than 1 more than the number that than can be placed on the region's surface. ASJC Scopus subject areas WebSpherical codes. A notion closely related to sphere packings of Euclidean spaces is that of spherical codes. Given Sn 1, the unit sphere in Rn, a -spherical code is a nite subset AˆSn 1 such that no two distinct x;y2Aare at an angular distance less than .
