Abstract

Narrowband interference, such as tone signal or low data rate modulated signal, can jam the communication link or degrade the performance of the communication link. It is, therefore, essential to develop a system to detect the presence of interference in communication payload onboard system susceptible to such types of interference. This paper aims at hardware implementation of frequency-domain narrowband interference detection scheme in a wideband spectrum. The performance of this scheme is analysed using Receiver Operating Characteristics (ROC), Probability of False Alarm (\(P_{\text {fa}}\)) and Probability of Detection (\(P_{\text {d}}\)). The detection scheme is implemented on Xilinx Virtex-7 FPGA board. Simulation and hardware results for tone signal or modulated signal are presented in the paper. The proposed scheme is suitable for digital processor which is employed in processing types of communication payloads.
