Hi eric,
Thanks for the reply, i have connected it to the
channel filters, i trying to do an estimate on
wireless channel coefficient. Therefore i'm trying to
capture the complex data received before
de-modulation. I havent have much success using vector
sink even when i set a range for the data captured,
all doesnt seems right.
Is there any blks that will be useful for my
experiment? Or do i have to write my own C++ blk to
process my needs. Thanks again.
regards,
ShinHan
The channel filter passes everything coming from the USRP and there's no
squelch here, so you'll get samples of the noise if you aren't
transmitting. Even if you are transmitting from another USRP, the
received signal is going to be sampled at the wrong time and have
frequency and phase offsets. I'm guessing that's what you mean by not right.
