I am trying to implement a channel sounder using gnuradio-companion. I
attached the snapshots of my transmitter and receiver with the email.
In the transmitter, a GLFSR float source is going through a root raised
cosine filter and then getting connected to the real input of USRP. I am
storing the complex I&Q samples in a sink file in the receiver.
I am correlating the complex samples with the reference GLFSR sequence
Expectedly, my setup is suffering from synchronization issue since I
have any synchronizer block in the receiver setup. This issue worsens
higher number of chips. Based on this setup, I have the following
Has anyone implemented a channel sounder in grc before? In an earlier
Re: [Discuss-gnuradio] DQPSK Modulation/Demodulation issue),
Jonathan said that there is a plan of re-implementing gr-sounder with
synchronization. I am just curious if anyone took that path.
How can I synchronize a continuous stream of I&Q data? If I put a
loop and M&M recovery block between the USRP source and the file sink,
it resolve the issue?
Any suggestion will be really helpful.
