I subscribed to Radio Electronics back in the late 80s, early 90s. I went looking for information on LTE signaling and came across this great tutorial they have published online. I thought I might share it. It was a great magazine but I stopped getting all mailed publications back then.
So, now I know what I’m seeing on the waterfall. Also, there is a very good frequency chart several pages in there. Better than the one that came on the sleeve of the LimeSDR.
