多径对BOC调制码跟踪环路的影响

Modulation Effect of Multipath on BOC Code Tracking Loop

研究了BOC调制码在相关器间距相同、带宽不同时多径干扰造成的最大码跟踪误差的对比。首先介绍了BOC调制的基本概念;其次从数学层面层层分析了BOC码字在相关器间距相同、带宽不同情况下的码跟踪误差的结果。结果表明带宽越大,码跟踪误差越大。

This paper studies the BOC modulation code in the same bandwidth correlator spacing, and multipath interference caused the greatest code tracking error comparison. First it introduced the BOC modulation of the basic concepts of mathematics, followed from layers of analysis of the results of BOC code in the same bandwidth correlator spacing, different instances of the code tracking error. The results show that the greater the bandwidth, the greater the code tracking error.
