TīmeklisIn [46], [47], Yan et al. proposed a real-world implementation using GNURadio-USRP2. It was a jamming-resilient wireless communication scheme using shown that the receiver could successfully decode the desired MIMO technology to cope with the reactive jamming attacks Wi-Fi signal in the presence of 20 dB stronger than the signals in … TīmeklisGNURadio is used to transmit the signal using output wav file from transmitter code and received signal is saved. we generate OFDM symbols and use IFFT to combine each …
