摘要
在建立Link-16接收机模型的基础上,分析了多径衰落对伪码序列自相关性的影响,推导了存在多径衰落时的误码率公式,最后通过仿真,研究了不同多径衰落程度下,接收机的误码性能。研究表明,Link-16数据链综合采用直接序列扩频(DS/SS)和跳频(FH/SS)技术,具有良好的抗多径干扰能力。
Based on the modeling of JTIDS receiver, the influence of multipath fading on PN code selfcorrelative characteristics is analyzed. And then considering for multipath fading, the error symbol rate （ESR） formula is modified. At last, the simulation is made to research the receiver＇s ESR perfonnance in presence of different extent multipath fading. The study shows that because of using direct-sequence spread spectrum （DS/SS） and frequency hopping spread spectrum （FH/SS）, Link-16 has a benign performance in counterworking multipath jamming.
