LimeSDR Workshop Materials Available

On 24th March we hosted a one day workshop in partnership with the BCS Open Source Specialist Group and Open Source Hardware User Group, that provided an introduction to software-defined radio and LimeSDR. Held at the BCS offices in central London, the event was free to attend and proved to be very popular, with participants ranging from industry experts to wireless novices.

The workshop was led by Principal RF Design Engineer at Lime Microsystems, Dr Danny Webster, who put together an excellent series of presentations supported by hands-on demonstrations.

Slide from presentation, What is LimeSDR?

The day started out by taking a look at the fundamental principles of wireless communication and digital radio, before exploring the LimeSDR platform and LMS7002M internals. Next the radio link was covered and key factors that contribute to its performance, followed by a look at methods of advanced digital radio communication and performance. Finally, LimeSDR boards were distributed and demos were run using Lime Suite, GNU Octave and Pothos.

The seven presentations and fifteen demos have all been published to GitHub. Hopefully these materials will prove to be of use to others starting out with LimeSDR, and we do plan to add to and improve these over time, with a view to them being used to support future workshops.

Despite the workshop going remarkably smoothly considering the various software that needed to be installed, packaging is one area where we intend to invest further effort, so as to make installing the requisite software across different O/S platforms even easier.

The talks were recorded, but the quality didn’t turn out as well as hoped and so we plan to re-record these at some point over the coming months.

  1. I recently received my LimeSDR board but am struggling to find a solid explanation of how all the software works together. Just to let you know where knowledge level is at, I am EE student at a Technical College hope to graduate soon but have had to do my own research to learn about FPGAs.

    I would love to get a copy of the recording even if the sound quality sucks. Audio engineering IS one thing I do know something about. If you can provide the recording I’d be happy to clean it up with post-prduction and send you the result. Alternatively (or hopefully in addition to), if you could point me to a good blog post or two about the initial software set up that might do just as well. Thanks
