Hello Jawad, I've made the changes you said. As you say, when I assign the Payload parameter to the number of samples of the block Random Source without introducing Delay, I get a BER value equal to 0. But what I need to introduce a noise source so that when I increase the power noise, also

Hi Antonio, I tried to open your GRC file. This must have been with a pretty old version of GNU Radio (which version are you using?). I strongly recommend getting a newer version of GNU Radio, because especially the OFDM code has improved a lot. By the way, a BER of about ~0.5 means that as many

Hi Gisle, rest assured, there's no unfriendliness towards MSVC -- it's just that we're currently really lacking people who have MSVC or even just Windows experience, and hence, problems like these can go unnoticed. Again, that's not a sign of anyone disliking MSVC, it's just that it's been a

You should just use matching versions of these files... kind of obviously. I wonder how this mix up happened; generally, you should just use the versions of things as they come with exactly your GNU Radio installation; probably, these files are under /usr/share/gnuradio/examples/digital or so.

Hi Ben, you will have to inspect the error, and it will tell you that the "options" object has no attribute "lo_offset". This means that the script tries to access member of the options variable that isn't there. Also, this allowed me to find out which benchmark_tx (there's two in GNU Radio)
