Wcdma use ovsf code as channel spread spectrum code . ovsf play an important role in . wcdma which offers flexible traffics Wcdma的信道扩频采用了长度可变的正交码序列,即ovsf码用作扩频码。
In order to solve the estimation problem of pn sequences itself , a code recovery algorithm based on subspace tracking is proposed 该算法通过应用past技术,求出两个主特征向量,实现扩频码序列的恢复。
The blind detection , parameters estimation and recovery of spreading sequences are the main contents of ds communication counter 直扩通信对抗包括直扩信号的盲检测、参数估计和扩频码序列恢复等内容。
Frame synchronization , acquisition and tracking of cc - codes are simulated . . continual special code insertion method is used in the simulation of frame synchronization 分别对帧同步、完全互补码的捕获、扩频码序列的跟踪进行了仿真研究。
This is true simply because the key scan code sequences will be different in the two cases , permitting the possibility that an input error is not detected on a non - native keyboard 情况确实如此,因为键扫描码序列在两种情况下将会不同,从而在非本地键盘上可能检测不到输入错误。
