Re: BER Calculations with QPSK Modulation and USRP

Hi John,

You'll almost certainly need to add a header to your data so you can synchronize the start of the transmission.

Hello,

I followed the PSK Demodulation tutorial, verified the results then made some changes so I could use it with a USRP B210. To do this I removed the channel and throttle blocks, and replaced them with the USRP Source and Sink blocks. I now would like to use a file as the data source and use a file sink to compare bit error rates of the transmitted data. However, it seems like the data is being shifted and I am unable to make sense of the received data. What changes must be made to perform the BER calculations?

Thanks for your help,

John
