이 편지에서는 새로운 수정된 RVD(실수값 분해)를 사용한 기븐스 회전(Givens Rotation)을 기반으로 하는 XNUMX단계 QR 분해 방식을 제시합니다. 첫 번째 단계에서 복소 기븐스 회전의 결과에 수정된 RVD를 적용하면 두 번째 단계에서 실제 기븐스 회전으로 제거해야 하는 XNUMX이 아닌 항의 수가 크게 줄어들고 계산 복잡도가 다음과 같은 분해 방식에 비해 크게 줄어듭니다. 기존의 RVD. 게다가 제안된 방식은 QR 분해의 하드웨어 설계에 적합하다. 평가에서는 제안된 QR 분해 기법이 계산 복잡도 측면에서 관련 연구에 비해 우수하다는 것을 보여주었다.

Abstract: In this letter, a two-stage QR decomposition scheme based on Givens rotation with novel modified real-value decomposition (RVD) is presented. With the modified RVD applied to the result from complex Givens rotation at first stage, the number of non-zero terms needed to be eliminated by real Givens rotation at second stage decreases greatly and the computational complexity is thereby reduced significantly compared to the decomposition scheme with the conventional RVD. Besides, the proposed scheme is suitable for the hardware design of QR decomposition. Evaluation shows that the proposed QR decomposition scheme is superior to the related works in terms of computational complexity.
