Make a general constellation object that calculates the Euclidean distance for hard decisions.

constell

List of constellation points (order of list matches pre_diff_code)

pre_diff_code

List of alphabet symbols (before applying any differential coding) (order of list matches constell)

rotational_symmetry

Number of rotations around unit circle that have the same representation.

dimensionality

Number of dimensions to the constellation.

normalization

Use AMPLITUDE_NORMALIZATION to normalize points to mean(abs(points))=1 (default), POWER_NORMALIZATION to normalize points to mean(abs(points)^2)=1 or NO_NORMALIZATION to keep the original amplitude.

Returns the constellation point that matches best.

Calculate Euclidean distance for any constellation.

Constellation which calculates the distance to each point in the constellation for decision making. Inefficient for large constellations.
