frequency acquisition造句

• In this thesis, a kind of 2-dimention signal acquisition method is presented which combines parallel pn code phase and carrier frequency acquisition, as a result the acquisition time is shortened greatly . besides, according to the fact that the detection of spread spectrum signals is always the key point in the receiving system
  在扩频信号的捕获过程中要求有较小的时延和较高的概率，本文介绍一种二维信号的捕获方法，这种方法结合伪pn码和载波频率的获取，捕获时延将大幅度降低，实际上，扩频信号的检测是接收系统的关键。
