A Study on Power Line Carrier System Using Spread Spectrum Technique.

확산대역 통신 방식을 이용한 전력선 반송 시스템에 관한 연구

There are Carrier Current Communication or Power line Carrier (PLC) Communication conducted data exchange using power line Which is installed existing indoor. Power line is possible to construct data link economically, on the other hand, have an inferior transmission environment such as irregular noise and severe level variation. The purpose of this paper is to present transmission possibility for PLC using spread spectrum technique. In the initial synchronization, established computer simulation for the S/N in relation to PN code generator. By using this result, construct the prototype SS system and then experiment the transmission characteristics.
