Abstract: This paper analyzes the signals of different commercial-off-the-shelf (COTS) privacy protection devices (PPDs), and compares several mitigation algorithms applied to these jamming signals. A review of the mitigation algorithms is presented, including the theoretical requirements. This paper allows an end-to-end comparison of the algorithms in terms of the final performance versus the implementation requirements. The properties of the interference signal, specifically the dynamics of the signal, greatly affects the mitigation capability. For high interference-to-noise ratio (INR), the filter-bank pulse blanking (FBPB) had the best performance followed by the Dual-frequency-domain adaptive filtering (FDAF). It was also shown that the modulation of the satellite signal selection has a significant influence on the performance.
