Oh, that's relatively easy--you multiply it with a complex signal at the
same frequency--that's
exactly how it's done in hardware, and it work
Marcus, Thanks for reply.
That is make sense, so the point become how to convert the signal to
baseband.

Hi Tom,
This is very old topic. I have read a DSP book. But I find that I still not
very understand channelizer.
Why in channelizer use low pass filter, in my imagine channelizer will use
band pass filter to filter each
channel like that: 600Mhz baseband signal have 4 channel each channel have
100K
Tom, thank u very much.

Yes, they are based on the same principle, but the decimator just
extracts the 1 channe
Thanks Tom.
if I really don't know how pfb_channelizer_ccf and pfb_decimator_ccf do, but
they seem

Not really. It's a very efficient algorithm
Hi Martin,
pfb_channelizer_ccf will seperate all channels, But I dont need each
channel.
I only need the channel I am interested in. Seperating all channels will eat
a lot of CPU resource.
I have check pfb_channelizer_ccf source, it finally use fftw to process
channelizer.
So can I directly use fft
Martin,
Thank u very much. But how much MHz is the limit in your word "a couple of
MHz"?

Short answer: you can go as wide as your CPU will handle.
If you only need a few channels but they're separated by a few MHz, use
the frequency xlating filters to bring each channel to baseband. If you
have a regularly-spaced band, use the channelizer.

Hi all, I need to receive many narrowband signals, but usrp hard ware only
provide 4 RX,
so I need to receive more than one narrowband signals per RX. Is my idea
possible?
I dont want to use more than one usrp to achieve that, anyway which will be
an
option if my first idea can't work.

I need to measure the time of flight with the accuracy in nanosecond, now I

Harley Thanks
I find another way call hyperbolic location method that is more accurate to
locate a cell phone. and what u said is correct, I must first get a phone's
communication. Now the easier way what I know is using openbts and usrp
build a gsm bts to communicate with cell phone. Am I right?
That cellphone triangulation stuff is just an urban legend:

Hello all,
I guess something changed on some packages and I am having problems to run
this code.
#if self.u.db[0][0].dbid() != usrp_dbid.BASIC_RX:
#sys.stderr.write('This code requires a Basic Rx board on Side

#sys.exit(1)
self.u.db[0] this gives me error in
