다중반송파 PAPR 감소를 위한 임계치 적용 적응 부최적 PTS 기법 연구
Multi-carriers PAPR Reduction Method using Adaptive Sub-optimal PTS with Threshold
초록
본 논문은 다중반송파로 인한 높은 최대 전력 대 평균 전력 비 감소를 위한 PTS 방식에서 시스템의 복잡도를 줄이기 위해 임계간을 활용하여 부 블록 계수를 최적화시키는 적응 부 최적 PTS 알고리즘을 제안한다. 제안 방법의 성능은 부 블록수가 4인 경우,
This paper proposes the adaptive suboptimal iterative algorithm using threshold to reduce system complexity in the PTS\`s. Performance of the proposed adaptive suboptimal iteration algorithm is represented in terms of iteration number and CDF. In the case of the number of sub-block is 4, the 10-3 PAPR of the proposed method and P S improved this by 0.4dB compared to Cimini\`s. And the complexity of the proposed method was reduced to nearly 22% for the PTS\`s and 44% for the Cimini\`s for 8dB threshold. For the 8 sub-blocks, the 10
