Hello SDR community,
I need some guidance into how vector manipulation works in GNU radio
companion.
Suppose I have the following MATLAB/Octave code:
Nf = 128;
Nt = 2^10;
F = zeros(Nt/2+1,1);
idxs= (1:round(Nt/Nf)/2:Nt/2)+1
phi = 2*pi*rand(Nf,1);

When replying, please edit your Subject line so it is more specific

Do this, please. I've changed it for you, but you should have done that
yourself.
If you want to learn about GNU Radio and how to use it with hardware,

I guess I can throw in a couple of pennies here...
Here at KIT we have a couple of students hacking GR-related projects,
and most of them get something running within reasonable time, provided
they've had some kind of previous programming experience.
Here's some of the advice I give them:

Is this the book you're talking about?
Let me know if you can find a copy.
I would definitely buy it if I could find it.
I'll take a look at the OOP chapter. I was playing with Objective C for a
while so have a little of OOP figured out, but just the basics. The USRP2
is a nice piece of hardware. There is a danger, on the WBX, of the LNA

I am currently trying to get some basic code working to test that my
shiny new USRP is working correctly. I have been going over the
code/examples/list archives for a few weeks on and off, but most of
the code examples are for the basic RX/TX boards, and I only have two
RFX2400's.

I have GNUradion up and running with the USRP board. I have two daughter
cards installed. One is the DBSRX, the second is the RFX1800, and I have a
3rd dauther board the TVRX that is not installed. I can get the thing to
respond, but I get an error on most of the python scripts. USRP Open
