Every memoryless modulation scheme can be described as M vectors in an
N-dimensional space.
So the chunck-to-symbols requires as dimensionality parameter the N and
then it needs this array of numbers
s11, s12, ... s1N,
s21, s22, s2N,
...
SM1, sM2, ... sMN
So a 2-dim orthogonal scheme is
N=2
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
Hello,
How can I specify symbol table and dimension for QAM in chunks_to_symbol
block? which modulation is indicating in fsm_utils.py by orth2 orth4?
Can anybody help me. I am new to this GnuRadio.
ThankYou
