摘要
为了提高现有预编码跳码直扩通信系统的抗干扰能力、通信保密性和反侦察能力,采用增加一个n级移位寄存器的方法,使跳码图案变换时间随信号码元跳变。通过研究分析,新系统在抗干扰、同步、反侦察以及保密性能等方面都有一定的改进。
To improve the anti-jamming ability,communication confidentiality and anti reconnaissance capability of existing pre-encoded code-hopping spread spectrum communication system,an added n level shift register method was used to transform the time of code-hopping with the signal element.Through the research and analysis,the new system is improved in some respects of anti-jamming,synchronization,anti reconnaissance and confidential performance.
