Systems methods and computer program products for generating and optimizing signal constellations

A system for constellation generation comprising:

• means for determining initial ucode boundaries;
• means for determining an initial minimum signal level spacing;
• means for generating a work constellation set based on the initial ucode boundaries and the initial minimum signal level spacing;
• means for iteratively adjusting the work constellation set so as to provide an adjusted work constellation set which achieves an error probability target;
• and
• means for iteratively pruning the adjusted work constellation set so as to provide a pruned work constellation set which achieves a power limit.
