Abstract
In this paper a novel jamming technique is presented. The idea of the proposed jamming technique is based on adding inphase and quadrature impairments to the jamming signal. The jammer is simply a quadrature phase shift keying signal. The bit error rate probability (BER) of the proposed jamming signal is derived analytically and validated with the aid of the software defined radio SystemVue design software. The standard multi input multi output (MIMO) wireless local area network (WLAN) IEEE802.11n communication system is chosen as the victim system. Its BER performance is simulated in the presence of the proposed jamming signal in multipath fading channel. Finally, the efficiency of the proposed jamming signal on the MIMO WLAN IEEE802.11n communication system is practically measured in the laboratory where a practical experiment is held and the efficiency of the proposed jamming signal is compared with the traditional single tone jamming signal. It will be shown practically that the proposed jamming technique outperforms the traditional single tone jamming signal by nearly 15 dBm on the impact of efficiently jam the MIMO WLAN IEEE802.11n communication system.
