hi everyone,
I am using the programs of DIGITAL-BERT folder to see the bit error
rate pattern versus the SNR. The given programs are for BPSK scheme. I tried
to change it for QPSK Scheme. But seems that I did not do it right. I am
giving the modified code in the programs . Please help me ou
hi everyone,
Is there any way for me to run the benchmark_tx and
benchmark_rx.py files in debugging mode so that I can see the entire flow
structure? I am curious to know the steps that take place from the calling
of the python script to the point where the modulated symbols are
transmit
Hello everyone,
I am using benchmark_tx.py and benchmark_rx.py programs to run the
transmission and reception of packets. I need some help in how to calculate
the received signal energy. May be this has to be done before the
demodulation step. Can some one help me with this.
Regards,

Hi Jonnathan,
Can u please share the programs which does the RSSI computation . I am
using the RFX2400 board. I need to plot BER against Receiver SNR. So, RSSI
is required.
Thank you
Amarnath

hi friends,
When I tried to print the Transmitter gain range by the following commands,
The output is as followss,

hi folks,
I am using BENCHMARK_TX.PY, BENCHMARK_RX.PY to test the
transmission and reception of signals. I have doubts regarding the outpu

hello everybody,
I wanted to test the USRP performance for various modulation
schemes by varying the power level of transmitted signal and plotting the
BER. Can i use one of the existing gnuradio-examples/python/ programs to do
this? How to check the power level of the transmitted signal
hi ,
I am using Fedora Core 11 OS. I have succesfully executed
benchmark_tx.py, benchmark_rx.py files. But coming to TUNNEL.PY I am unable
to ping to the other computer. Self ping is working.
Please help me, ( I am a beginner)
