Re: [Discuss-gnuradio] Generate a specific wave form

I'm very happy you're helping me to build. This is the first time I use 
GNURadio and it's very different of other softwares I usually work.

I can tell you my purpose, no problem at all. I'm trying to start a 
project about Cognitive Radio. For now, I want to build an Energy 
Detector.

A primary user might be sending a signal all the time (this is my signal 
source block). During this event, my Energy Detector will analyse the 
spectro and pass or not the signal of my primary user (the entire 
signal, everything that is being sent), because that's what a cognitive 
radio does. So, when it's possible, I will use the spectro to send a few 
informations.
When the spectro is being used (vector = 0, for example), I can't send 
information, because it would damage the signal of other person. I just 
want to send data, when the spectro is not being used (vector = 1).

To simulate this analysis, I was trying to use a vector source or a 
random source, because it's impossible to know when the spectro will be 
free; it's random.

I think it's easier to understand now. Thank you a lot for helping me 
here, guys.
