| 摘 要： | 自编码直接序列扩频通信由于提高了通信信号的隐蔽性,且保持了直接序列扩频通信技术原有的抗干扰性能,对改善军事抗干扰通信具有积极意义。根据自编码直接序列扩频通信的特点,设计出了原理样机,并提出和实现了一种基于帧变化并发送同步头的初始同步方案,效果良好。经过测试,所有性能指标均已达到预期目标,并且与单用户下的理论分析结论相吻合。 |

| Abstract: | While self-encoded spread spectrum communications(SESS) improve the concealable performance of communicating signals,they still maintain the anti-jamming ability of direct sequence spread spectrum communications.It is important to improve the signal security in military communication system.However,the design and trials of a test model which is based on SESS are designed.Meanwhile,a original synchronization scheme based on frame variety,in which the synchronous bits are need to be send,is proposed and applied.The design and the synchronous scheme are proved practical and all kinds of performance are satisfying. |
| Keywords: | self-encoded spread spectrum communication original synchronization |
