Hi Ali - please state the version of gnuardio you're using and post the
flowgraph used to generate your problem.

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
