Re: [Discuss-gnuradio] OFDM example from gr-digital with UHD

Jose,

If you set your file source to "repeat" it will produce an infinite
amount of samples, just like a sine would.
If you know you want to produce 10,000 packets (and see how many are
received), you only need to 96*10,000 samples.
Hence, you'll use the head block after the file source and set it to
960,000.

Best regards,
Marcus
