Method of equivalency transform for power spectrum density of track irregularity on central line from on left / right rail 左右轨道不平顺功率谱转换中心线功率谱的方法
This paper presents a power line communication method adopting the SSC ( spread spectrum carrier ) technology on the basis of analyzing the communication channels of the central metering and re - cording system. 本文在分析了集中抄表系统通信信道的基础上,提出来用扩频载波技术的电力线载波通信方式。
