Hello Antonny:
Your requirements are not very specific, but I think that the B200 should
meet your requirements for doing energy detection for Cognitive Radio. It
works well with GNU Radio, has transmit and receive ports, and is
full-duplex. Please let me know if you have any further questions.

no, you do not need to use something like a mute block.
The functionality you are looking for is already build into UHD (I'm
assuming you are using a USRP as your transmitting device)

Hello, Nathan!
Thank you for helping me. I took a look, but it's still expensive.
If I find only the board to buy (like BladeRF), it will be fine for me.
It's been a little difficult...
Please, if you know more reliable companies tell me. Thanks a lot.
Cheers,
Antony

Hi Antony,
really, get away from ruby-forum. It's mixing up replying order already
now, where your thread has had only two emails.
Really, as Nathan said, sign up directly -- it's so much more useable

My guess is that, it's because buffer of sink blocks don't have to be

Hi Monika,

Hi Jeon,
only output buffers are counted -- because they are the input buffers of
the next block downstream in your flow graph. Also, a single buffer
can only have one block writing to it, but multiple blocks reading from
it, so it's logical to only count the outputs; hence, sinks don't
count at

That pretty much depends on what /you/ want to measure -- obviously,
these bits are lost, so practically, this increases your BER.
If you want to demonstrate asymptotic behaviour, however, then you could
