Soft-decision decoding of linear block codes using efficient iterative G-space encodings
(2001)This paper proposes a sub-optimal maximum likelihood decoding algorithm for linear block codes. Given reliability information about each bit in the received word, our approach initially finds the set of most reliable "basis" ...

Soft-decision decoding of linear block codes using preprocessing
(2004)Two universally applicable preprocessing rules to improve iterative recoding algorithms, which utilize the most reliable basis (MRB), while focusing on order-w reprocessing, was investigated. The first preprocessing rule ...

Stable indirect adaptive control of continuous-time systems with no a priori knowledge on the parameters
(Publ by Pergamon Press Inc, 1993)A crucial drawback of indirect adaptive control is the stabilizability or controllability of the estimated plant model which is required in order to calculate the controller parameters. Loss of stabilizability at a particular ...

Stochastic nonlinear minimax filtering in continuous-time
(2001)This paper discusses nonlinear stochastic minimax games in which the minimizing player is the state estimate while the maximizing players are square-integrable stochastic disturbances. A pathwise optimization method is ...

A Systems Approach to Channel Equalization
(2003)In this paper we present a control theoretic frame-work for channel equalization. Channel equalization methods are used to mitigate the effects of inter-symbol interference (ISI). Traditional methods, maximize the signal ...

The use of curved elements in the finite element approximation of thin plates by high order p and hp methods
(2006)In this article we focus on the approximation of the Reissner-Mindlin (R-M) plate model by high-order p and hp versions of the Finite Element Method (FEM), in the case when the mesh includes curved elements
