Sorted QR decomposition (SQRD) has been extensively adopted for various multiple-input-multiple-output (MIMO) detectors, in which the sorting process incurs severe latency when it comes to larger-scale MIMO situations. This paper proposes a group-SQRD (GSQRD) algorithm to alleviate the latency ...

R[k][k]=||tmpk|| cQk=tmpk/R[k][k] Q calculated by Classical Gram Schmidt algorithm is not very orthogonal due to rounding errors. An example is provided by X. Jiao[1] The error introduced in q1 also cause errors in q2 and q3. We will discuss how to avoid this in the next ...
The present invention relates to a low-complexity MIMO detection based on QR decomposition algorithm, including an equivalent frequency domain channel matrix to calculate the corrected channel matrix and corrected channel matrix QR decomposition to obtain a unitary matrix Q and an upper triangular matrix...
However, an estimated signal obtained from the MMSE algorithm contains a bias which represents a self noise that degrades detection accuracy. It is well known in the art that MMSE technique can be simplified if a direct inversion of the channel matrix is replaced by the QR decomposition of an...
This means we’ll be able to celebrate 2015 as the golden anniversary of the practical QR algorithm. The variant of the QR algorithm used for the singular value decomposition (SVD) was published in 1965 by Gene Golub and Velvel Kahan and perfected in 1969 by Golub and Christian Reinsch....
From the calculations above, we have And the corresponding matrix multiplication form is QR-Decomposition aka QR-factorization definition: Let A be a real m*n matrix (m>=n). A can be decomposed into the product A=QR where Q (m*n) is orthogonal (Q^TQ=In) and R (n*n) is upper tr...
Hi, Did anyone know if there is a reference assembly implementation of the QR decomposition algorithm available for the C64x+. Thanks.
