These messages are decoded using a matrix representation of linear multivariable systems. Our approach consists of an optimal extended Kalman filter (EKF)-based observer, which is a linearization with time. We consider the observer with messages and the input with keys to be the transmitting agents. The optimal linearization technique is utilized to obtain the exact linear models of a chaotic system for operating states of interest. An EKF algorithm is used to estimate the parameters and states in which the message is already embedded. By combining the EKF with our optimal linear model, the message can be recovered on the receiver end. We provide numerical examples and simulations to demonstrate the effectiveness of our proposed methodology.","PeriodicalId":377853,"journal":{"name":"2014 IEEE Fifth International Conference on Communications and Electronics (ICCE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130637290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After projecting the 3D point clouds onto a natural 2D grid in the x, y plane, we triangulate the surface (actually, we compute a Delaunay triangulation of the 2D point cloud taking advantage of its regular structure). The main novelty of our approach is that the neighboring points of an edge ei are searched in a rectangle supported by the edge ei under consideration. The obtained results show that our method could process very fast, the initial shape of the surface is well preserved, and the topology of the output triangular mesh approximates the input surface of 3D point clouds.","PeriodicalId":377853,"journal":{"name":"2014 IEEE Fifth International Conference on Communications and Electronics (ICCE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132974435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The growth in quantity and complexity of signatures made matching task more challenge especially on general purpose processor. In this paper, we proposed an efficient architecture for matching Clam Antivirus (ClamAV) signatures on FPGA. We utilize Bloom filter technique for filtering input data and Bloomier filter technique for one round check suspect data. Our matching engine support up to 256 byte length signature and can handle both basic and regular expression signatures. Compare to previous approaches, our architecture is better memory utilization with 14%-64% less than previous works. Experiences on low-cost Altera Cyclone II show that our system can fit signature set with more than 43K characters size and is capable of 1 gigabit per second throughput.","PeriodicalId":377853,"journal":{"name":"2014 IEEE Fifth International Conference on Communications and Electronics (ICCE)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124043699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conventional CCD process technology with double or triple poly-silicon electrodes makes it very difficult to achieve folded CCDs. By utilizing a conventional CMOS process technology with only a single poly-silicon layer consisting of plurality of electrodes with a spacing of 150nm, we can design folded CCDs installed in each pixel. However, it is challenging to realize a practical folded CCD that has sufficient transfer efficiency and reasonable amount of full well capacity.

In the two-way relay system, each user terminal (UT) is required to estimate channel frequency responses (CFRs) for up and down links between both UTs and RS (Relay Station) precisely which are used in the demodulation of the other user's information data with frequency domain equalization. To satisfy the above requirement, this paper proposes a novel CFR estimation method for the SFBC MIMO-OFDM based two-way relay system which can achieve better CFR estimation accuracy and better BER performance even in the higher time-varying fading channel. The salient features of proposed system are to employ the SFBC technique both for data subcarriers in the pilot symbols and data symbols and to apply the Maximum Likelihood (ML) and Cubic Spline Interpolation methods to the estimated CFR at pilot subcarriers with Walsh codes in the estimation of CFR for the frequency axis and time axis, respectively. From the computer simulation results, this paper demonstrates the effectiveness of proposed system which can achieve higher signal quality with keeping higher transmission efficiency even in the higher time-varying fading channel.","PeriodicalId":377853,"journal":{"name":"2014 IEEE Fifth International Conference on Communications and Electronics (ICCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129456819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
