OFDM

[vimoca3]

Hi,

I'm new with labview and I'm trying to code an OFDM transceiver that I want to utilize with LTE and Wimax. I'm having trouble with the configuration parameters of the USRP. In particular, I'm having trouble with the selection  of the sample width parameter of the USRP. With a sample width of 8 bits, the program works perfectly (with both tecnologies, LTE and Wimax) but with 16 bits, the program doesn't work with LTE and labview shows this error message:

I don't know why labview shows this message, because I think that the Tx buffer is not empty as I created the OFDM simbols before the transmission has started. 

 I'd really appreciate if you could tell me why this problem occurs.

Thank you.

Can you please post the following details if possible ?

1. IQ rate that you are operating at. Does this behavior change if you vary it over a wide range ?

2. Device in use ?
