发明名称 Systems methods and computer program products for generating and optimizing signal constellations
摘要 Methods, systems and computer program products are provided for constellation generation which determine initial ucode boundaries and an initial minimum signal level spacing. A work constellation set is generated based on the initial ucode boundaries and the initial minimum signal level spacing. The work constellation set is then iteratively adjusted so as to provide an adjusted work constellation set which achieves an error probability target. The adjusted work constellation set is then iteratively pruned so as to provide a pruned work constellation set which achieves a power limit. The pruned work constellation set is then iteratively fine-tuned so as to provide a final constellation set which is within a specified tolerance of the error probability target and/or the power limit.
