Tiểu Luận Ứng dụng công nghê trải phổ vào việc truyền tin trên đường dây điện

ABSTRACT
The article introduces the spread spectrum technology and the application of this technology in the system of measurement, monitoring, controlling secondary load on power lines, especifically, the construction of diagrams of the remote control system using the spread spectrum technology, the analysis of changes in the transmission signals. In addition, spread spectrum technology has been studied and applied to the spread spectrum of words in wave transmission. Benefits of exploitation and application of the spread spectrum technology to the media signals on the lines are overcoming interference and securing information on the lines.
The interference overcoming and information security are based on the spread spectrum signals looking like interference which is difficult to be detected and stopped without appropriate equipment.
