Constellation Rect. Object: Difference between revisions

Revision as of 08:55, 22 April 2022

A version of Constellation Object specific to rectangular constellations. See Constellation Object for more usage info.

Symbol Map: List of alphabet symbols (before applying any differential coding) (order of list matches Constellation Points)

Constellation Points: List of constellation points (order of list matches Symbol Map)

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

Width Real Sectors: Width of each real sector to calculate decision boundaries.

Width Imaginary Sectors: Width of each imag sector to calculate decision boundaries.

Soft Bits Precision: The number of bits of precision used when generating the LUT.

Soft Decisions LUT: The soft decision LUT as a vector of tuples (vectors in C++) of soft decisions. Each element of the LUT is a vector of k-bit floats (where there are k bits/sample in the constellation).

This flowgraph is taken from the Guided_Tutorial_PSK_Demodulation tutorial.
