【摘要】 提出了一种跳频模式同步系统的有效抗干扰措施。该方法综合利用了纠错编码技术和直接序列扩谱技术对TOD同步信息进行处理,对单频干扰和跟踪式干扰均有较好的对抗能力,提高了系统性能。更多还原

【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.更多还原
