# wifi-ofdm A Software-Defined Radio implementation of IEEE 802.11a phisical layer on Gnuradio # Demo [![gr-wifi-ofdm demo video](http://img.youtube.com/vi/wYjP9WzbRcw/0.jpg)](http://www.youtube.com/watch?v=wYjP9WzbRcw) # Installation - prerequisite: gr-gadget - install gr-wifi-dsss: ``` cd gr-wifi-ofdm/ mkdir build cd build cmake .. make sudo make install ``` # Quick start `cd examples` and run the scripts in the folder. # Examples - 'wifi_ofdm_usrp_tx.grc': Transmitter script. Require one USRP connected to your computer. - 'wifi_ofdm_usrp_rx.grc': Receiver script. Also require one USRP connected. # Supported Rates The prototype supports the following data rates: - 6 Mbps - 9 Mbps - 12 Mbps - 18 Mbps - 24 Mbps - 36 Mbps - 48 Mbps - 54 Mbps # Notes For convenience, the current version of the prototype use hard-decision decoding in the convolutional-codes decoder and may therefore suffers from several dB bit-error-rate (BER) loss in low signal-to-noise ratio (SNR) regime.
