Video tutorial: OFDM packet transceivers with GNU radio

Orthogonal frequency-division multiplexing or OFDM is a method of encoding digital data on multiple carrier frequencies.

At this presentation from them recent FOSDEM 2014 conference in Brussels, Martin Braun explained the use of GNU Radio software and an SDR transceiver to explore OFDM block basics, how to set up links between nodes and how to start working on MACs.

Martin explains, “GNU Radio is a powerful tool for signal processing of any kind. It is very much suited for setting up any kind of communication link. In this tutorial, we will discuss how to set up a PHY that can be attached to an application and MAC layer in order to experiment with arbitrarily configured wireless networks.”
