导频信道 Pilot Channel通讯术语。每个码分多址基站连续发射的未调制直接序列扩频信号。导频信道使得用户站能够获得前向码分多址信道时限,提供相干解调相位参考,并且为各基站提供信号强度比较手段籍以确定何时进行切换。

至少一个导频信道输出提供确定估计分组差错率的基础。
At least one pilot channel output provides a basis to determine an estimated packet error rate.
在一个例子中,在实际接收所接收的信号之前分析导频信道。
In one example, a pilot channel is analyzed prior to actual receipt of the received signal.
由于公共导频信道无功率控制,有可能在接收端接收到的公共导频信号的功率很低,使得信道估计的误差变大。
Because there is no power control in CPICH, the received common pilot signal power is possibly very low if the mobile is far from the base station, and this time the channel estimates is inaccurate.
