Hi all,
I've managed to get to the same signal of the block "Constellation
Modulator" by using these blocks in concatenation:
{ --> repack bits --> differential encoder --> constellation encoder (or:
chunks to symbols) --> polyphase arbitrary resampler --> }
and tried them for bpak, qpsk, 8psk, and 16qam, and all OK.
This command digital.constellation_dqpsk().points() gets the following
points:
[(1.4142135381698608+1.4142135381698608j),
(-1.4142135381698608+1.4142135381698608j),
(-1.4142135381698608-1.4142135381698608j),
(1.4142135381698608-1.4142135381698608j)]
which is different from the documentation of DQPSK which says:
01 | 00
-------
11 | 10
I wonder how I can get the same result for DQPSK by using the above series
of blocks.
thanks
