Further to my query, i updated to 3.10.0. Now, the settings are working.
Thank you

Hi,
I am trying to learn from the wiki. In the illustrations, taps mentioned
for block Decimating FIR filter are -1, 0, 1 simulating difference filter
These values are not accepted while running the flowgraph. Program
seems to expect single value. I am using Gnuradio 3.8.1.0 on Ubuntu

Hi Ashish - the short of it is:
(samples/sec)/(symbols/sec) = samples/symbol
If the bandwidth is complex, then samples/sec = sampling rate in MHz,
and symbols/sec is the baud rate.
There are lot of reasons why you would get into trouble by just by
changing samples/symbol.

Dear All,
I have a situation where I need to demodulate a wide bandwidth signal (70
Mbps QPSK modulated, having 35 MHz IF bandwidth and sampled at 105 MSPS ) in
our lab. However, the signal generator will also add some amount of doppler
shift at a rate of 1 kHz/s. Which PSK demodulation blocks
find any max. speed data on these blocks.

We couldn't find any max. speed data on these blocks.
We are also considering to use some high speed GPU but could not find any
CUDA/ OpenCL based GNU Radio blocks.

Will try and take a look. One more thing is there any extra to do if the
PSK signal is +-67 degrees instead of nomal 90 degrees or the PSK
demodulator just handles it as usual.
I've never seen this before, but

IIRC you would just do the WBFM demod, then the PSK demod. See the
gr-rds: https://github.com/bastibl/gr-rds

Hello,
I had experimented with simple PSK reception with GNU-Radio when the
carrier is directly phase modulated.
However I would like to know how can I demodulate a PSK transmission which
is carried over a typical FM signal.
Kind regards,
Raydel

Hi all !
I am dealing with PSK (BPSK, QPSK, 8PSK) modulation/demodulation ; in
demodulation, I would want to retrieve the exact point (vector) before finding
the closest constellation point.
Is there any way to get it with d?psk.py codes or whatever else ?
Thanks in advance for your help.
