摘要/Abstract

摘要： 为了提高直扩系统抗截获、抗相关干扰性能，增加自编码跳码体制的工程可实现性，针对自编码跳码体制存在的直扩码同步困难问题，提出了一种新的自编码跳码扩谱体制——差分自编码跳码扩谱体制。该跳码扩谱体制借鉴差分跳频体制中G函数使频点伪随机跳变的特点，将G函数技术与自编码跳码体制相结合，使发送端当前时刻使用的直扩伪码序列由前一时刻码序列控制字和当前时刻的信息符号经G函数映射决定，利用G函数映射规则得到具有良好均匀性、随机性的伪码序列控制字。理论分析和仿真验证表明，提出的差分自编码跳码扩谱体制具有较好的抗截获、抗相关干扰性能，可有效降低数据传输的误码率，提高跳码系统的工程可实现性。

Abstract: 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.
