Hi,
Anything knows how to set up the parameters at Constellation sink in
GRC,
eg., theta, Alpha, max frequency, Mu,
I am doing some basic tests in GRC+two USRP2, trying to see how the
constellation look like. But it does not show good for DBPSK/DQPSK.
especially at RX, after downconverting from high frequency(2.4GHz), it
seems
to shows NOTHING but noise…But read from FFT sink, it did show the
signal.
I tried to find some documents on gnuradio+GRC, but nothing much on
that.
Thanks
