We develop a unified framework based on Krylov subspace expansion, which allows us to compare the performance of the conjugate gradient (CG) method, diagonal loading (DL), and a hybrid scheme. Our analysis shows that the DL method generally outperforms its alternatives, but at the cost of higher complexity. However, we also demonstrate that a proper implementation of the low-complexity CG method can also approach the performance of DL. Finally, we show that preconditioning degrades performance when the CE is poor.","lang":"eng"}],"_id":"40821","status":"public","doi":"10.1109/ICASSP.2012.6288548","date_created":"2023-01-30T11:51:57Z","year":"2012","author":[{"full_name":"Tong, Jun","last_name":"Tong","first_name":"Jun"},{"last_name":"Schreier","full_name":"Schreier, Peter J.","first_name":"Peter J."}],"user_id":"43497","citation":{"mla":"Tong, Jun, and Peter J.
