본 논문에서는 다음과 같은 차동 검출 기반의 다중 개루프 주파수 추정 기법을 제안한다. M- 빠른 초기 획득, 정확한 주파수 추정 및 넓은 주파수 범위를 동시에 달성하는 MPSK(ary Phase Shift Keying). 복잡성과 성능 사이에서 좋은 균형을 이루는 제안된 기법은 다음과 같이 작동합니다. 1) 서로 다른 지연을 갖는 차등 검출을 기반으로 하는 여러 주파수 오류 검출기(FED)로 구성됩니다. 2) FED에서 검출한 주파수 오차에 따라 개방 루프를 통해 넓은 범위(0심볼 차동 검출과 동일한 범위)의 주파수를 정확하게 추정합니다. 빠르게 시변하는 주파수를 추적하기 위한 실시간 기호별 연산의 경우 다른 주파수 추정 방식보다 복잡성이 적습니다. 분석, 수치 계산 및 컴퓨터 시뮬레이션을 통해 제안된 방식의 주파수 추정 오류가 Cramer-Rao 하한(CRLB)에 가깝다는 것을 확인했습니다(CRLB에서 제안한 방식의 점근적 열화는 약 5dB임). 넓은 주파수 범위를 유지하며 이 방식은 빠르게 시변하는 주파수를 추적할 수 있습니다.

Abstract: This paper proposes a multiple open-loop frequency estimation scheme based on differential detection for M-ary phase shift keying (MPSK), which accomplishes fast initial acquisition, precise frequency estimation and wide frequency coverage at the same time. The proposed scheme, which has a good trade-off between complexity and performance, operates as follows: 1) it consists of several frequency error detectors (FEDs) based on differential detection with different delays; 2) it precisely estimates frequency in a wide range (the same range of one symbol differential detection) by open-loop according to frequency errors detected by the FEDs. For real-time symbol-by-symbol operation in order to track fast time-varying frequency, it has a smaller complexity than the other frequency estimation schemes. It is confirmed by analysis, numerical calculation and computer simulation that the frequency estimation error of the proposed scheme is close to the Cramer-Rao lower bound (CRLB) (asymptotic degradation of the proposed scheme from the CRLB is about 0. 5 dB) while keeping a wide frequency coverage and this scheme can track fast time-varying frequency.
