Re: [Discuss-gnuradio] QAM and Chunks_to_Symbol

For small constellations, you can just specify the points manually. Here's an example for 16QAM. Just paste into the "Symbol Table" field in the block properties. The dimension is 1.

[complex(3,3), complex(3,1), complex(1,3), complex(1,1), complex(3,-3), complex(3,-1), complex(1,-3), complex(1,-1), complex(-3,3), complex(-3,1), complex(-1,3), complex(-1,1), complex(-3,-3), complex(-3,-1), complex(-1,-3), complex(-1,-1)]
