The platform +is thus built for pedagogical purposes and ought to show the various +parts of the signal processing chain of a receiver. -CONCLUSIONS +METHODS + +Two USRP B210 software defined radio (SDR) devices from Ettus Reasearch, +together with the open source software libraries GNU Radio and Dear +PyGUI were used to create a graphical user interface to display +waveforms from either a simulated or real wireless links affected by +multipath fading. The platform transmits a picture either using QPSK or +16ary QAM over a 2.4 GHz carrier and computes the empirical bit error +rate of the link. |
