A system and method for optimizing signal recognition in a light communication system by approximately maximizing the minimum distance between received constellation points; the method comprising identifying the constellation region containing points for transmitting symbols, identifying channel impairments, transforming the constellation region according to the channel impairments into a constellation region of potential received symbols, using signal processing circuitry to apply an algorithm that operates to maximize the minimum distance between constellation points to obtain a symbol constellation in the receiver constellation region, and inverting the transformation to obtain the designed transmitted-symbol constellation. The system comprises signal processing circuitry for performing a preferred methodology.
