Abstract

The phase noise spectrum distribution for remote controller using the BPSK mode and low data rate of 50 kbps was designed and proposed in this paper. In case of applying the BPSK that transmission performance is superior to FSK method, the performance degradations due to phase noise are generated. To minimize the phase noise effect, it is important to dispatch the digital signal in channel environment with required phase noise characteristics. To provide the terminal design technique and the proper channel environment with required phase noise characteristics, the phase noise spectrum distribution was designed for required phase noise characteristics. By analyzing the phase noise effects for damping factor and noise bandwidth of the carrier recovery circuit, the phase noise spectrum design that consider the damping factor and noise bandwidth was performed. Based on the IESS-308 standards, also, the phase noise effects was analyzed. The phase noise spectrum design techniques and phase noise spectrum that is suitable to remote controller were proposed.

본 논문에서는 BPSK 변조 방식과 50 kbps 저속 데이터 전송모드를 사용하는 원격제어 장치의 위상잡음 스펙트럼 분포를 설계하고 제시하였다. FSK 전송 방식보다 전송 성능이 우수한 BPSK 방식을 적용할 경우, 위상잡음에 의한 열화가 발생한다. 위상잡음에 의한 열화를 최소화하기 위해서는 요구 위상잡음을 갖는 채널 환경에서 신호를 전송하는 것이 중요하다. 요구 위상잡음 환경에 적합한 채널 환경 및 단말 장치 구현을 위하여 요구 성능을 만족하는 위상잡음 스펙트럼 분포를 설계한다. 위상잡음 설계 파라미터인 감쇠 정수와 잡음 대역폭에 대한 위상잡음 영향도를 해석하고 위상잡음 스펙트럼 분포 설계 파라미터로 적용하였다. IESS-308 위상잡음 특성을 기준으로 위상잡음 영향을 분석하고, 원격제어 장치에 적합한 위상잡음 스펙트럼 분포도와 설계 방법을 제시하였다.
