摘　　要：介绍了自编码扩频的原理,针对其自干扰现象提出了改进方法。仿真表明,虽然改进的自编码扩频序列与经典扩频序列的性能几乎相同,但通信的隐蔽性得到了增强。The paper introduces the theory of self-encoded spread spectrum and proposes an improved approach to its self-interference. The simulation results show that the performance of the improved self-encoded spread spectrum sequence is almost the same as the conventional spread spectrum sequence, but the capability of the covert communication is much strengthened.

关 键 词：扩频通信 自编码扩频 伪随机序列 自干扰
