We researched BP decoding algorithm based on variable-to-check information residual for LDPC code (VC-RBP) in this paper. It is a dynamic scheduling belief propagation using residuals, and has some advantages, such as fast decoding, good performance, and low complexity. It is similar to residual belief propagation (RBP),but has some difference in computing the residual message. Simulation shows that...
The parameter estimations are unstable when the determinant of the coefficient matrix of the normal equation is closed to 0 in least-squares estimation. The deviation of estimator is too great because of rounding error of calculator and it is hard to get the precise inverse of the coefficient matrix. A matrix function which is matrix power series was introduced in proposed method based on ridge estimation...
Sufficient conditions for the existence of conventional observers and Hinfin observers for a class of non-linear systems with one-sided Lipschitz condition are presented respectively and moreover by solving the Lyapunov equation and algebraic Riccati equation, explicit expression of corresponding observer gain matrix is obtained, which is a significant complement to the related literature, only proposing...
