We are open sourcing our LTE (4G) physical layer routines for those wishing to learn about LTE signals and waveforms and/or develop their own software stack as a basis for inexpensive LTE test and measurement equipment. The code is written in C/C++, interfaces with GNU Octave, and will be published before the end of the LimeNET campaign.

In this video Danny is showing the measured performance of each of the component signals for the Down and Up links, generated with a LimeSDR/LimeNET and displayed on a spectrum analyser.
