Due to a great many redundancy symbols, most of the existing differential space-time-frequency (DSTF) coding schemes suffer very low transmission rates. To overcome the disadvantage and obviously enhance the total transmission rate in a differential multiple-input-multiple-output (MIMO) orthogonal-frequency-division-multiplexing (OFDM) system, a rate embedded doubly directional DSTF coding scheme is proposed for doubly selective fading channels in this paper. High rate differentially coded matrices are embedded into proper time blocks and sub-carriers. In the frequency domain, both high rate non-unitary message matrices and low rate unitary message matrices are differentially transmitted alternately. In the time domain, all message matrices have full rates. Simulation results verify that, compared with those conventional DSTF coding schemes, the proposed scheme can achieve better error performances with higher transmission rates.

And then the matrices are submitted to singular-value decompositionfSVD).Finally,represent the feature points with eigenvectors obtained from sVD,and then construct matching matrix to obtain the final matching *** data and real world data both indicate that our method has a higher accuracy than theirs,and it can deal with the matching problem with more feature points effectively.

The transport-of-intensity equation describes the internal relationship between the intensity and phase distribution while wave is propagating in the mobile space. So the phase distribution can be solved by the use of the equation. It is an important measurement of non-interferometry. A new phase retrieval based on transport-of-intensity equation is presented. This method has the advantage of measuring only the close-up space on the plane of the intensity of light to the reconstruction of phase space. The problem of phase retrieval is translated into minimum of energy functional with linear convolution and total variation regularization. The one and two dimension experiment results show the correctness and validity of the algorithm.

This paper proposed a threshold RSA signature with traceable signers. In such scheme, there is a trusted center (TC), which generates all system parameters, the secret keys and the corresponding public keys of the group and all members, and exists a designated clerk, which creates a warrant recording the identities of the signers and other import information. Any t members can collaboratively generate the group signature with the help of the clerk, who verifies the validity of the partial signatures and combines them to the group signature. Any one can verify the correctness of the group signature by the public information and trace out to find the identities of the signers by the warrant.

The rapid development of the Web technology makes the Web mining become the focus of the current data mining, and the XML technology also becomes the standard of the data exchange on the Web. The paper introduces the Web mining technology, implements a frame of the Web mining based on the XML technology according to the advantage of XML in the data description, describes the implementation process of specific Web mining, and puts forward a promoting scheme on solving XML documents with VTD which solves the difficult mining problem on the Web caused by the most of the non-structure information.

To improve the accuracy and efficiency for solving the EFIE (electric field integral equation) by the method of moment, a novel scheme is put forward to improve the calculation precision based on the EFIE. Firstly, the inaccurate induced current is obtained by solving the EFIE under coarse mesh grids. Secondly, the scattered magnetic field at any given point on the surface of the object is calculated by the inaccurate induced current. Finally, the accurate induced current at any given point is determined through total magnetic field. The proposed approach is applied to the case of infinitely perfectly electric conducting circular cylinder and square cylinder. The numerical results are presented to demonstrate the high precision and efficiency when the size of mesh grid is large.
