I've established a temporary (60 day) FTP user account on our company FTP server to host the GNU Radio Rayleigh Fading code as it currently stands. I've placed the raw code that's relevant to this module there. It's not immediately ready to build however that won't take long for anyone familiar

Hi everyone! I have this problem with using gr_float_to_complex. I wanted to connect two sptr types wherein one contains floats while the other is an sptr type of gr_float_to_complex. Unfortunately, I always get an error message saying 'port number out of range.' What should I do? Sample Code: R

Thanks for your reply! I now found the error in my code regarding using gr_interleave. I had to pass two "sptr" types so that they can connect. So now I have another problem. Since my sources are all of "list" type that has been generated in Python without using any GNU Radio blocks; is there som

OK, I'll look at gathering up all relevant code and documentation and see what hosting options I have at this end. When I've got this sorted I'll post a link to the location of the files. In the meantime a little additional detail, taken from some of the comments in one of the header files. It

Hi Richard, This would be great! I have great use for this, and I'm sure many others would too. Did he generate any documentation showing his evaluation of his implementation, and any details of it? (like a final research paper). Could you make this code publicly available to the list so

expat from FC7 is used by the SDK 3.0 install. The magic kboot command IS the secret sauce. There is a nash update but I have not exercised it. After you get the text install done, if anyone is goofy enough to try and gnome in the thimble full of memory left ;-), they can change inittab.
