SISO OFDM TDD Example not working

[Wired_]

I was trying to use SISO OFDM example.

But to surprise Its not working in both the two cases:-

1. Loopback over air (.GVI gives no error but VLC is not receiving ant stream)

2 No loopback : An error is returned on turning on the Base station:-

The mobile station parameters are as in below figure:

Can somen one explain the source of inusoid wave? I am surprised at it!

After debugging figured out that same UDP sockets was being used simultaneously at base station and mobile node. 

I would recommend develoeprs to use highlight Execution procedure in debugginh mode in case of error handling. It gives a smooth feel of data flow and link associations.

Have you ever get the SISO OFDM TDD Example work with two device?

Currently, I am doing the SISO OFDM TDD Example like your work with two USRP-RIO 2953R. I can do streaming within one USRP-RIO with loop back selection in the example, but when it comes to two USRP-RIO streaming, one is base station and the other is UE,  but the demo seems to be not working.

Yes, like I said PSS is not locking hence it's just one way communcation with BS receiving self packets!

Can you try seeing if your PSS gets locked?

May be bypass the UDP queue and send a known packet to via PHY while loop.
