However, the most harmful noise for PLCC applications is that superimposed on a power line.
然而，最有害的噪声为PLCC应用是在输电线叠加的那。

Furthermore, it is very difficult to obtain a meaningful model of the PLCC channel, due to the time-variance of this channel.
此外，得到PLCC渠道的一个意味深长的模型，由于这种渠道的时间变化是非常难的。

In order to improve the practicability of the low voltage power line carrier communication (PLCC) some high level communication protocols should be applied.
