摘要
讨论了无线扩频定位系统的关键技术之一——扩频码的设计与实现。首先从实验的角度基于Logistic映射,分析了其所生成的混沌序列的部分相关特性及平衡性,给出了计算机仿真结果;最后从工程角度给出了易于实现的平衡GOLD码的设计方法。
The Design and implement of PN Code are discussed, which is one of the key techniques of wireless spread-spectrum positioning system. The correlation and balance properties of a special kind of chaos sequence i.e. Logistic-Map sequence are analyzed from the aspect of experiment and the computer simulation results are given. Finally the design method of balanced Gold code is presented which is easy for engineering realization.
