Dalam surat ini, skema penguraian QR dua peringkat berdasarkan putaran Givens dengan penguraian nilai sebenar (RVD) diubah suai novel dibentangkan. Dengan RVD yang diubah suai digunakan pada hasil daripada putaran Givens kompleks pada peringkat pertama, bilangan sebutan bukan sifar yang perlu dihapuskan dengan putaran Givens sebenar pada peringkat kedua berkurangan dengan banyak dan kerumitan pengiraan dikurangkan dengan ketara berbanding skema penguraian dengan RVD konvensional. Selain itu, skim yang dicadangkan adalah sesuai untuk reka bentuk perkakasan penguraian QR. Penilaian menunjukkan bahawa skim penguraian QR yang dicadangkan adalah lebih baik daripada kerja-kerja berkaitan dari segi kerumitan pengiraan.

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.
