Abstract:
The use of power lines for communication is a topic of great practical interest as well as active research and standardization activities. The introduction of communications signals onto an energized power line can cause significant distortion of the signal, especially at low frequencies. This paper describes a form of coherent pre-distortion for such communication signals which reduces the destructive interference. The approach can be optimized in several ways to mitigate distortion and achieve more efficient data transfer, and may be important in cases where low-frequency, low-rate carriers are used.
