A joint source-channel decoding method is designed to accelerate the iterative log-domain sum-product decoding procedure of LDPC codes as well as to improve the reconstructed image quality. Error resilience modes are used in the JPEG2000 source codec making it possible to provide useful source decoded information to the channel decoder. After each iteration, a tentative decoding is made and the...

This paper deals with the problem of robust beamforming and target power estimation in presence main-lobe interference frequency division array multiple-input multiple-output (FDA-MIMO) radar by adopting a weighting matrix at receiving end. Based on semi-definite programming (SDP) to solve covariance matrix, we propose two methods for estimating when has position error. Then, obtaining performi...

A new method for granulometric-parameter-based reconstruction of sediment-transport pathways is proposed and is termed P-GSTA (grain-size trend analysis using principal component analysis) herein. The main advantage of this method is its applicability to depositional environments involving mixed transport processes, for instance, fluvial, tidal, and wave-influenced environments. In the P-GSTA m...

In this paper, we focused on a design of an algorithm for decoupling multivariable systems based on generalized predictive control (DGPC). Two techniques are developed and compared for decoupling of TITO (Two-Input, Two-Output) processes. The first method is based on adding compensators between the upper and lower control paths. According to the second method, we use an adaptive error weighting...

The context-tree weighting algorithm [4] is a universal source coding algorithm for binary tree sources. In [2] the algorithm is modified for byte-oriented tree sources. This paper describes the context-tree branch-weighting algorithm, which can reduce the number of parameters for such sources, without increasing the complexity significantly.

In order to rapidly identify the source of water inrush in coal mine, and provide the theoretical basis for mine water damage prevention and control, fuzzy comprehensive evaluation model was established. The F statistics of water samples was normalized as the weight of fuzzy comprehensive evaluation for determining the source of water inrush in coal mine. The determination result of F statistic...
