Digital단측파대 변조기의 설계

Abstract

Weaver's analog단측파대 변조기의 원리와 Digital신호처리 기법을 적용하여 Digital단측파대 변조기의 특성을 computer simulation에 의하여 구하였다.

이러한 Digital단측파대 변조기는 주파수 분할 다중통신(FDM)시스템과 시분할 다중통신(TDM)시스템의 다중변환 시스템으로 사용할 수 있으며 Group band(60~108KHz)다중통신을 예로서 상호변환을 설명하고 시스템의 신호 대 잡음비(SNR)를 구하였다.

The digital Weaver's single side band(SSB) modulator is simulated, using its corresponding theory and digital processing techniques.

The simulated digital Weaver's modulator is used as a main part of the transmultiplexer which converts time division multiplexer(TDM) system to frequency division multiplexer(FDM) system.

The digital filters are designed for this purpose and the SNR of the overall system is calculated.
