본 논문에서 설명한 바와 같이, LDPC(low-density parity-check) 코딩된 직교 주파수 분할 다중화에서 부반송파 위상 제어 기반 PAPR(peak-to-average power ratio) 감소를 위한 위상 시퀀스 구성 및 블라인드 추정 방법을 제안한다. OFDM) 시스템. 송신기 측에서는 주어진 패리티 검사 행렬을 기반으로 위상 시퀀스 패턴이 구성됩니다. OFDM 신호의 PAPR은 PTS(Partial Transmit Sequence) 방식으로 WF(Weighting Factor) 조합의 수와 동일한 수의 후보 중에서 선택된 위상 시퀀스를 곱하여 감소시킨다. 수신기 측에서는 디코딩 기능을 사용하여 위상 시퀀스를 맹목적으로 추정합니다. 즉, 제한된 수의 가능한 위상 시퀀스 후보 중에서 가장 가능성이 높은 위상 시퀀스를 각 후보의 합산 계산 결과를 비교하여 추론합니다. 컴퓨터 시뮬레이션 결과에 따르면 QPSK-OFDM 및 16QAM-OFDM 신호의 PAPR은 감쇠된 3.7 경로 Rayleigh의 완벽한 추정과 비교하여 BLER(블록 오류율) 성능의 현저한 저하 없이 각각 약 4.0dB 및 12dB만큼 감소할 수 있음을 보여줍니다. 퇴색 상태.

Abstract: As described in this paper, construction and blind estimation methods of phase sequences are proposed for subcarrier-phase control based peak-to-average power ratio (PAPR) reduction in low-density parity-check (LDPC)-coded orthogonal frequency division multiplexing (OFDM) systems. On the transmitter side, phase sequence patterns are constructed based on a given parity-check matrix. The PAPR of the OFDM signal is reduced by multiplying the constructed phase sequence selected from the same number of candidates as the number of weighting factor (WF) combinations in a partial transmit sequence (PTS) method. On the receiver side, the phase sequence is estimated blindly using the decoding function, i.e., the most likely phase sequence among a limited number of possible phase sequence candidates is inferred by comparing the sum-product calculation results of each candidate. Computer simulation results show that PAPR of QPSK-OFDM and 16QAM-OFDM signals can be reduced respectively by about 3.7 dB and 4.0 dB without marked degradation of the block error rate (BLER) performance as compared to perfect estimation in an attenuated 12-path Rayleigh fading condition.
