抗阻塞 meaning in Chinese
antiblocking
Examples
- We analyzed the anti - jam and band inside anti - interfere performance of the system , and the low probability intercept ( lpi ) of the traditional direct sequence spread spectrum ( dsss ) modulations in the uav platform ' s applications . so a new modulation technique using a multi - level pseudo noise ( pn ) code has been presented . the new multi - level pn code is built from a high speed pn code through a low passed filter ( lpf )
分析了系统抗阻塞式干扰和抗带内频带干扰的性能，以及常规bpsk qpsk - dsss调制在无人机通信中存在的安全隐患，提出了一种用多电平pn码进行扩频调制的方法：采用高速pn码，经过低通滤波器，产生多电平pn码进行直序扩频调制，能在低信噪比情况下有效抵抗平方率检测器对系统载波的检测。
