Transient Theoretical Analysis of Diffusion RLS Algorithm for Cyclostationary Colored Inputs

چکیده
Convergence of the diffusion RLS (DRLS) algorithm to steady-state has been extensively studied in literature, whereas no analysis its transient convergence behavior reported yet. In this letter, we conduct a theoretical DRLS for cyclostationary colored inputs, mean and mean-square error sense. The resulting analytical models allows us thoroughly investigate over adaptive networks such complex scenarios. Simulation results support accuracy correctness findings.

QR-RLS Algorithm for Error Diffusion of Color Images
Printing color images on color printers and displaying them on computer monitors requires a significant reduction of physically distinct colors, which causes degradation in image quality. An eecient method to improve the display quality of a quantized image is error diiusion which works by distributing the previous quantization errors to neighboring pixels exploiting the eye's averaging of colo...
متن کاملSensitivity Analysis of Transversal RLS Algorithms With Correlated Inputs
In this contribution it is shown that the sensitivity analysis predicts that the mean square excess error is the same for both correlated and white inputs. Correlation increases the variance about the mean square excess error. We also present a stable finite precision RLS algorithm. Many adaptive filtering problems can be cast as a systems identification problem. Consider the desired signal d(n...
متن کاملA stack-based chaotic algorithm for encryption of colored images
In this paper, a new method is presented for encryption of colored images. This method is based on using stack data structure and chaos which make the image encryption algorithm more efficient and robust. In the proposed algorithm, a series of data whose range is between 0 and 3 is generated using chaotic logistic system. Then, the original image is divided into four subimages, and these four i...

15 صفحه اولRegularization of the RLS Algorithm
SUMMARY Regularization plays a fundamental role in adaptive filtering. There are, very likely, many different ways to regularize an adaptive filter. In this letter, we propose one possible way to do it based on a condition that makes intuitively sense. From this condition, we show how to regularize the recursive least-squares (RLS) algorithm.
