본 논문에서는 클래스 IV 부분 응답 신호 SSB 시스템의 전송 성능을 제시하고 전력 효율을 향상시킬 수 있는 방법을 제안한다. 디지털 신호의 SSB 전송에는 DC 성분이 없는 라인 코드가 사용되었습니다. 부분 응답 시그널링과 같은 라인 코드 유형은 변조 상태를 증가시키고 결과적으로 전력 효율을 감소시킵니다. 이러한 장애를 극복하기 위해 직교 위상 검출을 가정하여 "재필터링 및 결합"이라는 새로운 복조 방법이 제안되었습니다. 복조된 직교 채널은 힐베르트 필터로 다시 필터링되고 동위상 채널과 결합됩니다. 새로운 복조 방식을 통해 BER 성능이 향상되고 전력 효율이 3dB 향상되는 것을 컴퓨터 시뮬레이션을 통해 확인했습니다.

Abstract: This paper presents the transmission performance of a class-IV partial-response signaling SSB system and proposes a method that can improve its power efficiency. A line code that has no dc component has been used in the SSB transmission of digital signals. The type of line code, such as a partial-response signaling, increases the modulation states, and as a result, decreases the power efficiency. To overcome this obstacle, a new demodulation method called "re-filtering and combining" is proposed on the assumption of orthogonal phase detection. The demodulated quadrature channel is re-filtered by a Hilbert filter and is combined with the in-phase channel. It is confirmed by computer simulations that the new demodulation method improves the BER performance and a 3 dB improvement of the power efficiency is obtained.
