The No-hit-zone Design Method of Frequency Hopping Sequence Based on RS Encoding
Received date: 2019-04-15
Online published: 2025-02-12
Frequency hopping spread spectrum (FHSS) owns better anti multi-path and anti-fading, which can enhance the performance of anti-intercepting and anti-jamming. Aiming at the shortcoming of the high collision probability of the frequency hopping sequence generated by RS (63,2) encoding, an enhanced frequency hopping sequence method is designed, which can enhance the frequency gap and reduce the collision probability. The simulation results show that the Hamming cross-correlation of the improved sequence decreases significantly, meanwhile the frequency gap increases obviously, and the anti-multiple access interference(MAI)performance improve significantly when accessing FHSS network in collision free area.
