Partial-Band Jamming Suppression with a Noncoherent CPM Detector

In this paper, we proposed a partial-band jamming suppression algorithm especially for a slow frequency hopping system. In this system, continuous phase modulation (CPM) is adopted, and the algorithm is based on the iterative noncoherent CPM detection and the jamming state information (JSI) estimation. The complexity of the system is reduced by iterative tree search scheme rather than the exhaustive tree search and multiple symbol differential detector (MSDD) schemes. The simulation results demonstrate that the algorithm performs well for the partial-band jamming suppression. Moreover, the difference of the performances due to varieties of demodulation parameters is discussed.
