摘要：
The problem of defining a distance spectra for a finite subset of a trellis is dealt with. As the basic examples of such subsets the codes with a constant normalization (spheric codes) and codes with a limited normalization (spheric clusters) are considered. The problem is solved by using the extended production function of a trellis. The results of calculations for concrete examples are given. The asymptotic of a distance spectra is investigated.
