Constellation Rect. Object: Difference between revisions

Revision as of 12:44, 6 June 2020

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.

 == Example Flowgraph ==
-Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI.  Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately.  The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
