BER Based Impact Analysis of Jamming Signals for Fading Channels

For any communication system, jammers are one of the major reasons leading to denial of service to the desired end user of the system. These jammers could be deployed as part of some security protocol to stop RF communication in a particular area or with an objective to intentionally disrupt communication services. To counter the latter case, anti-jamming capability is a crucial and desired characteristic of any communication system. The performance analysis of such jamming systems presented in previous studies has mainly considered the effect of jamming under AWGN channel conditions. No significant analysis has been done considering the effect of multipath fading. In this paper, the authors have investigated the effect of jamming signal for commonly used digital modulation techniques in a more realistic environment by considering the fading aspect of communication channels. Bit Error Rate (BER) expressions have been obtained for different modulation techniques to analyze the effect of jamming signal. The proposed model provides a more realistic scenario for system designers to calculate and estimate the outage limits for an anti-jamming communication system.
