Synchronous Carrier Wave Interference Suppression Based on Accumulation and Average in Loran-C

摘要：

To improve real-time performance of narrow band interference (NBI) suppression in Loran-C system,algorithm of accumulation and average is presented based on the analysis of the structure of Loran-C pulses. After that, effects of synchronous carrier wave interference(CWI) and the interference whose frequency is integral multiple of 0.5kHz upper or lower than that of Loran-C signal are simulated and analyzed. The simulation results show that the presented algorithm can suppress the CWI mentioned above effectively. Moreover,the mean square error of the algorithm does not change with signal to interference ratio(SIR),and is always on the level of 10-6. And then,the validity of the algorithm is proved by the experiment.
