Abstract
The V.34 high-speed modem combines a number of advanced techniques includin g constellation shaping by shell mapping. This technique makes use of some functions representing the number of ring combinations with a given cost. I n this correspondence, closed-form expressions for these functions are give n and used in the constellation shaping by the shell-mapping algorithm.
