在卫星移动通信中应用突发扩频技术实现终端的全球随遇接入有重要的应用价值.针对突发通信时间极短、突发时刻随机和卫星移动通信信道带宽窄等条件，以及保障安全可靠的接入和传输更多有效信息的需求，本文提出了一种采用私有、随路信息方式对扩频序列进行动态加密，增加截获、破译难度的短码同步方案，加密后的长码采用混沌扩频码扩频，获得较高的安全性；同时在接收单元采用一种改进的RAKE技术提高信号接收性能.为了验证算法的有效性，在卫星终端原理样机上进行了性能测试验证.信息速率为1.2 kbps、码片速率为3.069 Mcps.在SNR小于

Abstract

It is of great value to apply burst spread spectrum technology in satellite mobile communication to realize the global random encounter access of terminals. In the condition such as extremely short burst communication time

random burst time and narrow channel bandwidth of satellite mobile communication

as well as the requirement of ensuring reliable access and transmitting more effective information

a short code synchronization scheme that uses private and random information to encrypt the spread spectrum sequence in action is proposed in this paper

increasing the difficulty of interception and decoding. The encrypted long code is spread by chaotic spread spectrum code to obtain high security. At the same time

an improved rake technology is adopted in the receiving unit to improve reception performance of signal. In order to verify the effectiveness of the algorithm

the performance test is carried out on the principle prototype of satellite terminal. The information rate is 1.2 kbps

and the chip rate is 3.069 Mcps. Under condition of SNR less than -15 dB

reliable acquisition and channel synchronization of DSSS spread spectrum signal can be realized in 2 ms.
