阐述了在复用电力线载波机(PLC)中传输远动信号时,数据速率与信道带宽的关系,提出了用4DPSK调制解调方式在PLC机上音频带中传输1200Bd远动数据的方法,并给出了具体实现的原理框图。
The relationship between data rate and channel bandwidth when transmitting remote signals in multiplexed power line carrier (PLC) is described. A method of transmitting 1200Bd tele-data in the upper audio frequency band of PLC by 4DPSK modem is proposed. Out of the concrete realization of the principle block diagram.
