Hi
I was just wondering if it is possible to implement a state machine logic
using GNURadio. Where each state is a block and incoming data passes
through these states. I want to be able to control which block gets
executed when, based on some state transition logic which I will define.
For exampl

Dear Marcus,
Regarding the excellent SDR Academy programme and other programmes there,
especially the ones concerning space satellite and deep space signal
reception - would you suggest that my pc with the sdr's as well should be
brought in for practice, or it will be organized as lecture type eve
I'll reiterate: what do you do tree account for real world channels? You
haven't told us *anything* about your transceiver aside from it using BPSK.
Best regards,

I don't understand -- are you seeing nothing at all or are you seeing ISI?
Again: what's your pulse shape? Does it fit in your channel bandwidth? Do you
fulfill the Nyquist ISI criteria?
As you know, there's solid theory in why ISI occurs, why you need to limit your
signal's bandwidth and how
Hi,
On any multipath channel there will be some isi. What do you do to suppress
that? What kind of filtering/pulse shaping do you do? Does matched filtering
solve your issue?
Best regards,

Hello everyone,
I tried to implement bpsk system.I am successful with the transmission part
but I am able to see the ISI when I am observing the constellation at the
transmitter side. I tried to design the receiver side same as the
transmitter but just the opposite way i.e, using block Psk demod a
