Hi Jale -
Best regards, apologies for not writing in English.
I'm doing a project for a tx and rx with OFDM modulation.
The transmitter does not present any kind of problem to traffic.
But in the receiver after the OFDM DEMOD block, the original signal is not regenerated.
If someone could help me, please.
It should be noted that I am working with USRP B10 cards
Subsequently, I must calculate the BER of the Recepted signal
I attach the files.
Thank you.

A few thoughts:
* get the Tx signal to be closer to [-1, +1] ... [-0.6, +0.6] isn't full scale, and the Tx signal will be that much weaker.
* you don't note how you are transmitting the data from Tx to Rx ... wirelessly? via a cable (hopefully with in-line attenuation)? the Rx signal could be very small if the Tx -> Rx distance is too great.
* If you change the OFDM parameters, does the system work ... for example using the default values that the OFDM Mod and Demod use? At least in some cases for GR OFDM, using anything but the defaults doesn't work without significant effort and knowledge of how to get it working.
Hope this is useful! - MLD
