See full text

A method of transmitting data. The method comprises preliminarily providing a modulation scheme comprising an N-symbol constellation defined in an M-dimensional space, wherein N<2M, and a composite distance between a given pair of symbols within the constellation increases with increasing Hamming distance between data words encoded in each of those symbols. During run-time, a data signal to be transmitted is encoded as symbols of the constellation, and modulated onto at least M dimensions of a carrier light in accordance with the symbols.
