Re: [Discuss-gnuradio] QAM and Chunks_to_Symbol

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

table =

1 ,0,
0, 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
