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。
