I am not sure what you mean by high frequency. Is the bandwidth of your
signal 32Mhz or is your signal on a 32Mhz carrier?
Take a look at digital down conversion:

The fft sink shows you frequency components from -sample_rate/2 to
sample_rat

Hi Brian and All,
Thanks for your last reply about implementing CDMA in GNURadio. I read some
materials on synchronization and also the OFDM examples in GNURadio. Is that
possible if I add a Code block into the OFDM block diagram to implement
MC-CDMA?
For the OFDM Transmit path:

Hi all,
I am planning to write a sink module that accepts mpeg transport stream
and displays to the screen.
Due to the variable bit rate nature of mpeg stream, this sink will
consume the input at variable rate.
I plan to use the generic gr_block as base class as it provides the most
flexibility
Hello!
My question is the followed: If I have a high frequency Signal ( for
example: 32MHz ) and if I want to see a FFT of this Signal, how can i
do? If I try with FFT sink, it's doesn't working beacause the sampling
frequency have to 2* higher to be. What is the solution?

Hi All,
I'm a newbie here. Recently, I got an USRP. But I can not make it work. Even
the exmaples of GNURadio doesn't work properly. Could you please give me
some help? Thanks.
I tried it on 4 PCs. None of them can pass 32MB/s usb test with
usrp_benchmark_usb.py.
Most of them can only passed 2MB/
