Webcharacterize the asymptotic behavior of right-orthogonally invariant random matrices (Theorem 4). Although these results are closely linked to the conjectured limits implied by the replica method, they are proven rigorously here under mild assumptions. Due to space constraints many of the proofs are either sketched or omitted. C. Notation We ... WebThis paper derives state evolution (SE) equations to design the Bayes-optimal denoiser in CAMP. Numerical results imply that CAMP with the Bayes-optimal denoiser--called Bayes-optimal CAMP--can achieve the Bayes-optimal performance for right-orthogonally invariant sensing matrices with low-to-moderate condition numbers. chuggington watch cartoon online
