It measures the minimum number of substitutions required to change one string into the other, or the number of errors that transformed one string into the other. The process of detecting errors in a sequence of bits is determined by comparing this sequence to a dictionary of encodings, if found then the pattern is correct, otherwise an error has occurred. In order to correct the errors, the original pattern is substituted with the closest pattern in the dictionary, i.e. the pattern with the smallest hamming distance from the original. A code having a minimum Hamming distance d, can typically detect up to d - 1 and correct up to (d - 1)/2 errors in a code word. In this paper we are going to study the possibility to design an encoding scheme by using random patterns in the dictionary that are created by a secure encryption algorithm, and we are going to test the error correction capabilities of our code. For our study, we used a model in which the code words are represented by whole numbers and an error of size r will change the message number by ± r. So, for example, a single error in the message x=7 will change the value of x to 8 or 6, and if x=7 is received as y=10 then an error of size 3 has occurred. The study will be as follows: if we have K numbers selected randomly from {1, 2, 3 ... N} where K<;N, what is the expected minimum distance between the numbers that we will get? To reach our objective, we designed a tool that will find the smallest distance between some K selected numbers out of N, and we were able to show theoretically and practically that for any N, there exist K<;N such that the minimum distance between those K selected numbers is definitely going to be 1, and therefore we cannot detect or correct any error.","PeriodicalId":245530,"journal":{"name":"2012 2nd International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128816900","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}

Compared to the other, previously published works, the paper presents simulations based on very complex link model containing all important parts of an optical wireless communication system. The link model allows setting of the basic parameters of laser diode, transmitting lens, laser beam, receiver lens, and parameters of photodiode and front-end amplifier of an optical receiver and also allows selection of the modulation format and many other electrical parameters. For modeling the turbulence effect on the link performance the modified Rytov scintillation theory have been used. The paper extends already published analysis of scintillation loss performed for a plane wave to a spherical wave which includes, in addition, the propagation loss. Communication link performances are calculated not only in dependence on general quantities such as scintillation index or signal to noise ratio, but they are evaluated for real link model parameters such as transmission range or power link margin.","PeriodicalId":245530,"journal":{"name":"2012 2nd International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128823057","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}

Folding in retiming can also reduce the resource utilization and power consumption. This transformation requires computation of critical path and shortest path at various stages. In this particular work, a FPGA based path finder is designed to compute critical path and shortest path in the Data Flow Graphs (DFGs). Since this path computation is performed using FPGA based IC, the speed of retiming transformation increases. This also reduces the resource utilization of the general purpose machine in which retiming transformation is usually performed. Critical path in sequential circuit is defined as the longest path between any two storage components. This determines the minimum feasible clock period for any sequential circuit. We need to compute the critical path before we apply retiming transformation to any digital Signal Processing block. Similarly shortest path computation is required in retiming while solving the system inequalities in the constraint graph. In this work, shortest path computation is performed using Floyd-Warshall algorithm. Since FPGA based hardware for path solvers performs much faster when compared to general purpose processor [where actual retiming is done], the speed with which the retiming transformation is performed increases. Xilinx ISE design suit is used with device as SPARTEN3E XC3S250E for the work presented.","PeriodicalId":245530,"journal":{"name":"2012 2nd International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126176216","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}
