Research on abnormal hopping recognition method of multi-channel frequency hopping communication system based on adaptive feedback channel modulation

  • Received Date: 2020-09-09
  • Multi-channel frequency hopping (FH) communication systems are often disturbed by channel hopping, which results in channel anomalies.In order to solve this problem, an adaptive feedback channel modulation method was designed to identify the abnormal hopping of a multi-channel FH communication system. Firstly, the channel model of the multi-channel FH communication system was constructed, and the output conversion control was developed by combining the space channel equalization method, and the carrier modulation and beam output were adjusted by the decision feedback regulation method, then the channel feedback equalization control model of the multi-channel FH communication system was established. Based on this, the adaptive parameter adjustment method was used to carry out the equalization design of the multi-channel FH communication system and the optimized parameter identification, the channel output gain was improved through spread spectrum processing, and then the abnormal hopping position information was identified according to the extracted results of channel difference feature points. The simulation results showed that this method was more accurate in identifying the abnormal hopping of multi-channel FH communication system, and the communication channel equalization was better after the application of this method.
