Constellation Rect. Object

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

Parameters

 * 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.


 * Real Sectors
 * Number of sectors the real axis is split in to.


 * Imaginary Sectors
 * Number of sectors the imag axis is split in to.


 * 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).

Example Flowgraph
This flowgraph is taken from the QPSK_Mod_and_Demod tutorial.
