Tail-biting codes are the main control channel coding form for the LTE system. The WAVA algorithm is one of the widely used as the decoding algorithm of tail-biting codes. To fully make use of the information on the algebra structure of the tail-biting codes, we combined the WAVA algorithm with the algebraic decoding, and proposed a new joint probability-algebraic decoding algorithm. Simulation results...
This paper researches the fragment mosaic model of fragments from the same paper. By analyzing the character of Chinese character, we classify the fragments into different group. And for different situation that fragments were cut, we put forward the 0–1 integer programming model to solve the problem. The matching degree of different fragment decided by the cosine similarity of the fragments. The...
The concept of strong designated verifier signature was proposed by Jakobsson in 1996. The signature only permits the designated verifier to verify its correction, while any other parties cannot verifier it and do not trust authenticity of the signature from the designated verifier. The reason why they don't trust it is that the designated verifier can create an indistinguishable signature for all...
Support vector machine (SVM) is a machine learning method developed in the mid-1990s based on statistical learning theory. SVM classifier is currently more popular classifier. This paper presents a boundary detection technique for retaining the potential support vector. Through seeking to structural risk minimization of the SVM, it improves the learning generalization ability and achieves the minimization...
Sphere Decoding (SD) algorithm was proposed to effectively find the Maximum Likelihood (ML) solution. However, the computational complexity of SD is still too high when SNR is low or the dimension of the problem is large. In this paper, we propose three improved schemes based on contraction factor to reduce the complexity of sphere decoding. In the proposed schemes, a factor was introduced for speeding...
Finite element method (FEM) was used for the design of a piezoelectric rotary actuator by means of inchworm motion. This piezoelectric actuator can achieve large-stroke rotary with a high resolution. The common used cylinder rotor was replaced by one new designed rotor with a regular corrugated surface. The effect of the corrugated contact surface between the rotor and the stator was analyzed by finite...
The sphere decoding (SD) algorithm based on Schnorr-Euchner (S-E) strategy can reduce the complexity for multiple-input multiple-output (MIMO) systems to find the maximum likelihood (ML) solution by updating the search radius whenever a new lattice point was found. In this paper, we propose an improved scheme to reduce the complexity of sphere decoding. In the new method, a factor was introduced for...
We are given a set of items, and a set of knapsacks. Both the weight and the profit of an item are functions of the knapsack, and each knapsack has a positive real capacity. A restriction is setting that the number of the items which are admissible to each knapsack is no more than k, and these items are taken as input for each knapsack. We consider two following objectives: (1) maximizing the total...
A method for the synthesis of solution process-based MWCNT/Ag NPs composite ink is presented in this paper. Thin films as electrode or interconnect materials for flexible electronic device were produced after sintering the CNT/ Ag tracks. Given that CNTs has large specific surface area and high specific surface energy, it's challenging to evenly disperse composite ink with CNTs in the metal matrix...
Rapid developments of microelectronics technology constantly promote the information technology revolution driving sorts of new electronic products to be produced. With the continuous requirements of light, thin and small for new generation of electronic devices, the traditional rigid substrate electronic products have gradually dissatisfied those demands for mobile products and have promoted the...
Link prediction in networks is of both theoretical interest and practical significance in many branches of science, and a great number of algorithms are based on microscale (common neighbours) or mesoscale (communities) information of observed networks. Either microscale or mesoscale methods are limited in the understanding of the topological properties at the corresponding scales. This article proposes...
Link prediction has significance in both theoretical interest and practical operation. Many methods via local and global structural information have been proposed. Methods based on local information like the Common Neighbours Index(CN) successfully reduce the computational expense but suffer from poor prediction performance. In this article, we put forward a new approach, namely Betweenness and Common...
In this paper, we propose an improved pilot-based blind (PBB) phase estimation method named mixed-polar-amplitude-modulation (MPAM-PBB) method for coherent optical orthogonal frequency-division multiplexing (CO-OFDM). In the previous PBB methods, all the selected so-called pilot subcarriers (PSs) are loaded with bipolar amplitude modulation (AM) format signal. In MPAM-PBB method, half of the selected...
The multiple knapsack problem is to pack some items into given knapsacks, such that the sum of the knapsack profits is maximized. This paper is concerned with a variant of the multiple knapsack problem, called the multiple knapsack problem with compatible bipartite graph (MKPCBG), where two items can be packed into the same knapsack only if their corresponding vertices are adjacent in the given compatible...
Dell Advanced Infrastructure Manager (AIM) is a software that separates the physical elements in the data center from how to control them. It is convenient to share a pool of backup servers that are ready to take over any other failed server's role. In this paper we integrate Matlab Distributed Computing Server (MDCS) with AIM to build a reliable, efficient platform for scientific computations. The...
In PCM/FM remote sensing receiving system, when the bit rate is above 1Mbps, the signal suffers frequency select fading, which causes the serious inter-symbol interference (ISI); power allowance can no longer guarantee the system quota. Besides signal reflection such as buildings, ground, mountains and atmospheric refraction eventually become the multipath interference signals. Thus an adaptive filter...
In order to solve the problem of trusted authentication between terminals, as well as terminals and the server, and to establish a safe and reliable network environment, a remote attestation scheme design based on the identity and attribute certificates is proposed. Through a third-party certification body, which authenticates the identity and attributes of the Trusted Platform, this design ensures...

Thus, from theory and example, we give a rapid calculation based on MATLAB tool,...
The orthogonal wavelet lowpassed filters coefficients with arbitrary length are constructed in this paper. When N=2k and N= 2k−1, the general analytic constructions of orthogonal wavelet filters are put forward, respectively. The famous Daubechies filter and many other wavelet filters are tested by the proposed novel method, which is very useful for wavelet theory research and many applications areas...
Recently, cloud computing is increasingly becoming the focus of attention at home and abroad. When the big data storage is become the core of cloud computing system, cloud computing system would evolve into a cloud storage system. With rapidly development of cloud computing, cloud storage has become one of most popular research field. HDFS (Hadoop Distributed File System) has a powerful data storage...
