I am trying to install uhd. However, it keeps complain: couldn't find
boost. Actually, my boost is in /usr/include/boost. The version is 1.65.
Does anybody know why the boost couldn't be found?
Besides, I am pretty sure there is on uhd installed via apt ( not in /usr
either )
I connected USRP200 to my host computer via USB3.0. I set up the VM
adaptor's IP address and subnet mask as 192.168.10.1 & 255.255.255.0 via
Windows 10.
However, when I run "uhd_find_devices", I got: linux; GNU C++ version
7.3.0; Boost_106501; UHD_003.010.003.000-0-unknown No UHD Devices Found

I need to implement a signal processing block in the FPGA of the USRP. Then
connect this block to other block done via C++.
Is there a tutorial on how to implement a DSP block in FPGA in USRP for
this purpose?
Thanks in advance!

Is there a box that can do the BER calculation given the clean input data
bit stream directly from the source and the demodulated data bit stream on
the receiver side?

Can the constant be a complex number? For example, Can I set the constant
to be 1.0*j, which should rotate the constellation graph by 90 degrees?

Reinstalled the workspace for gnuradio. Tried a test on the new workspace
with the howto example, but didn't create the Python QA test file. Instead,
I directly modified the "square_ff_impl.cc" file. "cmake" command has
passed. While doing "make" command, I got:

We use "repeat" variable in a file source to show whether or not we want to
repeatedly play the file. In my module, I generated a limited length of
random data, and I use "bool repeat" to show whether or not I want the
limited length of data to be repeatedly played. However, when I run the
module,
Hi,
I guess this is a very simple question:

there is a upsampling module I could use at hand in gnuradio companion?
Besides, for BPSK modulation, how should I set up the constellation sink
because it looks like it can
For some reason, I need to send out a sine wave for 1 second, wait for 5
seconds, and finally send out another sine wave for another 1 second. Is it
possible to make such a source in gnu radio directly, based on the existing
gnu radio blocks?
Thanks in advance!
Is there a good book for an "overview of C++11/14" so somebody with a very

Hello everybody,
Are there any good tutorials or videos on youtube that explains how to do

I created a module named detector0 with one input argument: int len. In the
python qa file, I set the len to 20. However, when I issued the command:
ctest -V -R detector0, I got the following error:

I have played with the taps in this Polyphase Clock Sync block using

I guess I may have a misunderstanding on the usage of
firdes.root_raised_cosine
(double gain, double sampling_freq, double symbol_rate, double alpha, int
ntaps) function.
In the flowgraph, the parameters are set up as follows:
samp_rate = 32k;
upsampling_rate (sps) = 4;
