| Abstract: |
| This paper introduces a Smart Home system based on low-voltage power line channel(PLC) and its corresponding software and hardware designing architecture. Orthogonal Multi-Carrier Modulation(OMCM) is adopted to overcome the frequency selectivity and time variation of low-voltage power line channel. Moreover this paper describes a flexible way to construct PLC networks, which boosts the expansibility of system. Finally,it discusses the application and practicability of the design. |
