The phase noise is usually specified, depending on the carrier offset, as a single-sideband phase noise referenced to the carrier offset.
相位噪声总是具体的， 取决于载波偏移， 作为相对于载波偏移的一个单边带噪声。

This article briefly introduces the produce of transmitting noise caused by converter valves, noise propagation mode, and its affection to adjacent power line carrier channels.
简要介绍了换流站换流阀的传导噪声的产生、传播方式以及对邻近的电力线载波通道的影响。

From signal tonoise ratio analysis of the modulation signal, we choose the phase modulation method as the suitable carrier modulation for the twisted-pair.
