Hi everyone,

I am trying to tx and rx a binary file using USRP B210. The GUI sink at
transmitters side shows a regular LTE signal. However, at receivers
side, I am getting a lot of noise and the signal is hardly visible.
The binary file is generated using openLTE's lte_fdd_dl_file_gen.py. The
file format is gr_complex.
I have attached my flowgraph and the scope results as well. Kindly help
me figure out where am I wrong.
I was thinking there is something wrong in the file, but then I can see
it at the transmitters side. So I am assuming it is okay. Also, I tried
to increase and decrease the tx and rx gain but with very little
success.
Any help would be appreciated.
The binary file generated has the following specs:
fs=30720000Hz
band=14
bandwidth=10MHz
Thanks,
Sushree
