一种新的自编码跳码扩谱体制.

In order to improve the anti-interception, anti-coherent interference performance and feasibility of self-encoded code-hopping system, a new kind of communication technology combining G function and self-encoded code-hopping technology is proposed, which is called differential self-encoded code-hopping system. This technology is used to solve the synchronization problem of self-encoded code-hopping system. The novel system adopts G function to generate control words of pseudo-random sequence which own good uniformity and randomicity. Simulated results show that differential self-encoded code-hopping system has better performance on anti-coherent interception, anti-interference and bit error rates. In addition, the engineering feasibility of code-hopping system is improved. [ABSTRACT FROM AUTHOR]
