Abstract

Recent studies have been conducted on powerline communications as a viable alternative to the spread of the spread of the Internet and the Internet as the chief source of information act in the information age, the internet does not reach local Last Mile Solution. Powerline communication, but because it has been designed to transfer power to the high frequency signal to be sent when the close of wireless communications services impacted. The notch filters of a common way to eliminate the interference are used. In this paper, a dynamic high-performance notch filter applying WDF performance was verified through MATLAB and was implemented using a TI's TMS320C6416T DSP board.

최근 인터넷이 주 정보원으로 작용하고 인터넷의 보급이 확산되는 정보화시대에 인터넷 망이 닿지 않는 지역의 Last Mile Solution에 적합한 대안으로서 전력선 통신에 관한 연구가 진행되고 있다. 하지만, 전력선 통신은 전력을 전송하도록 설계되었기 때문에 높은 고주파 신호를 보내게 되면 부근의 무선통신 서비스에 영향을 주게 된다. 이러한 간섭을 제거하기 위해서 일반적인 방법으로는 Notch filter를 주로 사용한다. 본 논문에서는 WDF 방식을 적용한 동적 고성능 Notch filter를 MATLAB을 통해 성능을 확인하였고 TI사의 TMS320C6416T DSP 보드를 이용하여 구현하였다.
