Abstract
According to embodiments, there is provided a method apparatus for determining an encoding scheme for transmission of encoded data across a communications channel. The method includes determining the encoding scheme at a design Signal-to-Noise Ratio and evaluating a Frame Error Rate of the encoding scheme. If the FER is not within a target range, the method further includes modifying the encoding scheme until the evaluated FER is within the target range. There is further provided a method and apparatus for mapping bit labels to a plurality of symbols in a constellation, wherein the constellation are organisable into a plurality of sets and each bit label includes a plurality of bit positions. The method includes determining a distance metric between sets and merging pairs of sets according to the distance metric. The method further includes assigning a value to a bit position for bit labels of symbols in the merged set.
