OOT Module for GNU Radio This OOT module includes blocks to build a packetized transceiver system using USRPs. It was developed as part of a M.Sc thesis at RWTH-Aachen University. This transceiver is part of a mm-wave research platform used at the Institute for Networked System.

##Install

mkdir build
cd build
cmake ..
make && make install

##Usage For an example which uses most of the parts of this project see the transceiver.grc in the examples folder.

This flowgraph sets up a transceiver that accepts UDP input and forwards output also via UDP. It is intended for use with a USRP x3x0 SDR device.

In oder to use this example you have to compile the following hierarchical blocks using GRC:

• grc/inets_tx_phy.grc
• grc/inets_rx_phy.grc
• grc/inets_radio.grc

How to use develop_mode to debug:

1. Set parameter 'develop_mode' to the index of the blocks to display the debugging information.
