Abstract

Enumerative sphere shaping of N-dimensional constellations is discussed. It is proven that a finite-precision number representation is suitable for use in two enumerative indexing algorithms: Enumerative sphere shaping and Divide Conquer (DC) shaping. This representation decreases the storage complexities of these methods significantly. DC is the basis of the well-known shell mapping algorithm and thus our approximations also apply there.
