Dear all,I have downloaded the fpga code of USRP2 from:
git://ettus.sourcerepo.com/ettus/uhd.git
and compile with ISE10.1 like this:
cd uhd\fpga\usrp2\top\u2_rev3
make
but the output file in uhd\fpga\usrp2\top\u2_rev3\build is 0 byte.Is there
anything else I sould do?Is there any difference betwee
Hi,:
I'm learning about polyphase channelizer, and I have been reading fred
harris' paper "Digital Receivers and Transmitters Using Polyphase Filter
Banks for Wireless Communications". I have also played with the Matlab
programs at the end of the paper. What I'm trying to do next is to use

Hi all, I check gnuradio code found set_bw( ) is not implemented in
db_flexrf_900_rx_mimo_b.
So can I set bandwidth for rfx1800 board?

I tried an experiment this evening with my 6-channel VLF receiver, which
uses a sound-card (sampled at 96KHz or 192KHz) to sample
a VLF loop antenna and amplifier, and then do power detection (and
other things) over six discrete channels, arbitrarily spaced.
The version that I've been using u

Actually, the total bandwidth is 40MHz, due to c
