carrier detection meaning in English

载波检波
载波检验

Antenatal diagnosis and carrier detection of pseudohypertrophic muscular dystrophy
假肥大型肌营养不良症产前诊断与遗传咨询
This property can be used to monitor the state of the carrier detection line for a port
此属性可用于监视端口的载波检测行的状态。
The method was correlate search and fft carrier detection , which could solve the problem of the capture of the spread spectrum code under the condition of low snr and big frequency offset . we also put forward a method , shift receiving window and correlate with local sequence , which not only could solve the problem of symbol synchronization but also could acquire the statistics of the multipath . then we utilized the results of the channel estimation and the technology of rake receiver to decode the received spread spectrum sequence and acquire rude information
方案中提出了：相关搜索、 fft检测信号载波的方法，解决了低信噪比、大频差条件下扩频码的同步捕获难题；滑动相关完成位同步的方法，解决了低信噪比下的同步问题；在时域利用相关进行信道估计，然后利用rake接收技术完成相关解扩的方法，一定程度上解决了多径衰落影响解扩性能的问题。
