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 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?

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

module,
Hi,
I guess this is a very simple question:

there is a upsampling module I could use at hand in gnuradio companion?

because it looks like it can on
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

programming overview book can always help!

I created a module named detector0 with one input argument: int len. In the

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;
