Hi Manuel,
I haven't taken a very detailed look at your flowgraph (the symbol rate
being 10e6 with a sampling rate of 400kHz seems odd), but:
* 400kHz sampling rate means that the complex baseband you get out of
your USRP represents but 400kHz of bandwidth. Your let's have a look
at you
Hello
I am trying to cross compile GNURadio by SDK and follow instructions from

I download GNURadio source file from Github. when I do CMAKE, it gives me

I can just repeat myself for the third time.
You are starting gdb without the executable; python in this case.

Thanks for all, Martin and Marcus!
I changed the Random Source block to a File Source block and put a File Sink
block on the receiver side ... It is working well ;) (I am transmitting a
.txt file)
Another question... to use the block "Error Rate" to calculate the BER of
the system, I just need p

Hi Martin,
Thank you.
1.Why the packet length should be larger than 32 bits?Can you explain it?
2.For example,I'm using the OFDM example in gnuradio.If i want to have a
working CRC,I must set the length>=4?Is 4 OK?
3.Is the packet length means that the original length(for example len=a) or

Hii
I want to generate BER vs SNR graph for BPSK and match it with the
theoritical result.
Is there any block which i can use?
If not what should i do ?
