Hi all,
thanks to Bastian i have solved my problem. So the problem was due to zero
padding between regenerated frames as Bastian said : "The padding shouldn't
be all zeros but contain a small amount
of noise. If you send an all-zeros stream of samples, the receiver will
constantly divide by zero,
Hi,
thanks for quick reply. What I am trying to do is to regenerate noise-free
wifi frames, which I already captured with HackRf. So I m receiving wifi
samples with hack RF then and save both the samples and decoded frames in
files. I use the decoded pcap file to regenerate the wifi frames. I se
Hi,
Thanks for your reply. I could not find out how can I solve it. But this
problem comes only when I receive from a file source. Even tough when send
the IQ samples that I captured with Hackrf, which i saved in a file, it
encounters the same problem.Is there any some blocks can be alternative
Hello everyone,
I am using gr-ieee802_11 to regenerate wifi packets. I receive packets with
HackRf and regenerate the same packet with transmitter and now I want to
look whether they look the similar but some packets are not received. I
enabled MAC decode debug and it gives this error when it mis
would be grateful for your help
Thanks
Best Regards

Hi Marcus,
thank your very much for your reply . In Pictures attached there are my
receiver and transmitter. So with HackRf I have received some wifi packets.
And in my transmitter I read the Pcap file which contains those wifi packets
that I received and sending them all to the transmitter to cre
Dear all,
I am using gr-ieee802_11 Transceiver to analyze wifi signals.
I receive samples and retransmit the same IQ samples wit Tx and save
them in file, but when I try to use that IQ samples from file to receive
them from file source some packets are not received, even though they
are successful
Hi Marcus,
thanks for your reply and valuable comment on EVM. My problem with TX is
that I do not know how to connect my File source with the Transmittter
block? Of course I can receive the transmitted data by connecting file sink
parallel to USRP sink as you said but if I save my data Bytes from
Dear all,
I am using Bastian Bloessl's gr-ieee802_11 OFDM Transceiver for my
Thesis. I have used the Rx to captured the WiFi frames and saved them in
a file and also Pcap file of them. Now I want to compare the frames that
I received with the Original ones in order to check the change in
transmitt
