| 摘 要： | 电力线载波通信系统通常应用正交调制有效地抵消带外和带内干扰信号以实现单边带调制,应用多进制正交幅度调制(M-QAM)实现高速数据传输,将正交调制作为复信号来研究可以简化对通信系统的分析和设计.文中介绍了复信号的定义、实调制与复调制、用复低通信号表示带通信号、单边带复调制与解调,以及数字单边带韦瓦复调制在数字化载波机中的应用.

| Abstract: | Power line carrier communication systems usually use quadrature modulation to effectively cancel out-band signals and in-band interfering signals to implement single-side-band (SSB) modulation and use M-QAM to implement high speed data transmission. The analysis and design can be simplified by considering quadrature modulation as the complex signal. The definition of the complex signal, real modulation and complex modulation, the complex low-pass signal representation of real bandpass signal, SSB complex modulation and demodulation, and the application of digital SSB Weaver complex modulation in the digitized carrier communication are described. |
