调制接收机 meaning in Chinese
modulated receiver
Examples
- Secondly , we apply tk operator to the cross - correlation of received signal code and pn code to separate the multi - paths . it comes to a conclusion that tk operator can separate the multi - paths within less than the chip period accurately of spread - spectrum system with space - modulation by simulation . at last , we apply this algorithm to the practical signal collected by gps tap , and from the result we can drop a conclusion the tk algorithm is practical
本文首先阐述了时空调制扩频信号原理以及在多径干扰下时空调制接收机的性能和teager - kaiser接收机的原理;接着对时空调制扩频系统的解调信号与伪码的互相关函数采用tk接收机进行多径分离,仿真结果表明, tk接收机对时延在一个码片内的时空调制扩频通信多径信号有很好的分离效果;最后用数据采集器对一个gps信号进行接收和多径的估计,验证了该算法在实际的运用中对多径的扩频信号有很好的分离效果。
