Hi All
I just wonder anybody may know how interfacing GNU Radio to Code Composer
Studio can be done.
Thanks

Hello everyone,
I hope this post is not out of line but I would like to purchase, trade,

retail price. If anyone can help me out, I would really appreciate it.

Essentially I disagree with everything Martin says here.
The 3.X support of FFT'w from FFTW is completely transparent to the end
user for everything we are doing since the API on 3.1 and 3.2 are
identical. You do a plan, you execute by passing the plan. About the

Cell support is very very nice.

You will have to calibrate _everything_ in the path, and of course
that includes the signal processing in the FPGA as well as anything in
the host-based signal processing path. And yes, pretty much all of

It's easier to push the separated data into your FIFOs rather than pull them in.

Hi,
I have created a wiki page describing what USB packet parsing could look
like for the transmit chain:

I am wondering what you think of it; if it is completely wrong or if it
could work with some modifications. I made a wiki page so you can mo

No particular fault. However, the outputs from the USRP are almost
always some kind of complex values. They may be encoded as 16-bit I &
Q, or 8-bit I & Q or 4-bit or 2-bit or 1-bit. The question is how do
we want to deal with them downstream from the USRP? The existing
usrp.source_s could b

I'm trying to "calibrate" the flow-graph of the am_rcv_plasma_mod.py so
that the values displayed in the final window represent actual input

The first step to do this would be to account for the internal gain; so I

I just want to send a signal that is time shifted, or how to make my own
