Hello Guys,
I am experiencing some problems in transmitting/receiving at frequencies around
900MHz for WBX board. While, I am able to do so cleanly at 900MHz, other center
frequencies are not.
The signal bandwidth : 50 KHz
The sampling frequency: 200 KHz
I have tried 901MHz , 900.1MHz, 910MHz

Hello Guys,
What is the IF frequency of the WBX board? I could not find this in the WBX
documentations. Any pointers? Thank you.

Hello Guys,
Was anyone able to get Probe MPSK SNR block to work under GRC environment. I
could not get it to work. I used it with the function probe and used the
"noise_variance" method and the appropriate block ID values but the problem is
that upon running, it is not updating the value inside

Step 1) Lets avoid issues with multiple versions of gnuradio and stuff
like that. Remove **all** gnuradio stuff

Hello Guys,
How can I debug the problem when I type grc in the terminal, I get:
File "/usr/local/bin/grc/", line 33, in

ImportError: No module named grc
I got the dial_tone.py working so I do not think it is a python path problem
but I am not sure, also when I

Hello Guys,
I was wondering if any efforts have been made to apply parallel programming
techniques in GNU radio projects. I have seen a project of building an OFDM
transceiver using a cluster and MPI technique. However, in case of using

Hello Swapna,
The SNR in wireless channel cannot be measured but it can be "estimated". One
way to do that for constant envelope modulation such as PSK is by measuring the
variance in the received signal envelope. Ideally you should receive a constant
stable envelope of your signal. However, du
Hello Einar,
Knowing your modulation type can simplify your symbol and carrier
synchronization design. However, if your are not restricted with certain
modulation type and you just want to use an arbitrary modulation to get you
going then I suggest to use differential coding such as D-BPSK whic
Hi Guys,
Let me add my two cents here:
The chip synchronization can take care of the symbol synch since the chip
correlation does not produce maximum values unless the symbol timing is
correct. Normally, and what I mean by normally is typical cases to the best of
my knowledge, the synchroniza
