can some one send me a flow graph of QPSK transmitter and receiver, this
flow graph should include a root raised cosine filter, qpsk generator,
multipath channel, additive gaussian noise source, snr estimator and
feed
back, interpolator, carrier recovery using bandedge filters, timing
recovery using poly phs clock sync, lms equalizer, coastas detector.

I tried doing the same but having hard time executing the flow graph.

That’s a pretty large ask.

Can you be more specific in the hard time you’re having executing your
flow
graph? Can you post your flow graph to the internet and link to it? Is
this for simulation or is there hardware in the loop?

You’ll probably have a much higher degree of success if you ask specific
questions about your (shared) graph instead of asking someone to
re-create
a graph you’re trying to make.
