An Anti-jamming Method for Frequency Hopping Synchronization |
|
() |
Abstract: |
An effective anti-jamming method for synchronization of Frequency Hopping (FH) system is provided. According to this method, the TOD(Time of Date)message for FH synchronization is transmitted with both error correction code and direct sequence (DS) spread spectrum. The method has good performance both in Fixed Broadband Jamming and Tracing Jamming environment. |
