Output voltage is regulated by duty cycle control of semiconductor switch of switch mode dc-dc converters. The voltage gain and efficiency of practical switching regulators deviate from ideal values at extreme duty cycles. Also, desired gain /attenuation is not achievable at high/low duty cycles. In applications where high gain or high attenuation of voltage is desired with acceptable energy conversion efficiency, hybrid dc-dc switching converters are used. Hybrid dc-dc converters are combination of voltage multiplier/division circuit with appropriate SMPS circuits. By incorporating voltage multiplier/division cell with conventional converters like Buck, Boost, Buck-Boost, Ĉuk and SEPIC converters, desired voltage gain (either very low or very high) may be achieved at acceptable energy conversion efficiency. In the present work with an aim to attain very high voltage gain by conventional Boost topologies, a new voltage multiplier cell consisting of multiple inductors and diodes is proposed. The proposed voltage multiplier cell can be duplicated in multiple number.","PeriodicalId":240329,"journal":{"name":"2016 3rd International Conference on Electrical Engineering and Information Communication Technology (ICEEICT)","volume":"168 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114304910","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 analysis is presented to find the expression for the signal current and multi access interference (MAI) current at the output of an equal gain combiner (EGC) in presence of atmospheric channel effect, atmospheric turbulence and pointing error. The performance results in terms of BER are evaluated for different values of code lengths, number of receiver antennas, number of simultaneous user and the system parameters. It is found that, significant degradation in the receiver BER performance due to the atmospheric channel effect and in presence of pointing error can be substantially reduced by increasing the number of photodetectors. Further improvement in the receiver sensitivity can be obtained by increasing the optical code length for a given number of user at a given BER of 10−9. For example, at a BER of 10−9 and number of user K=16 sensitivity improvement due to receive diversity is found to be 2.15 dB, 2.35 dB, 2.6 dB corresponding to processing gain of 64, 256 and 512 respectively for number of photodetector receiver of 4.","PeriodicalId":240329,"journal":{"name":"2016 3rd International Conference on Electrical Engineering and Information Communication Technology (ICEEICT)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114691389","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}

It is one of the top-ten listed fundamentally important problems in networking. It causes many important data to be lost. Wastage of network resources results from this. It makes the network easily become gridlocked, with little or no data being transported end-to-end. To protect data transfer from this problem various models of TCP are proposed. These variants differ from each other based on the congestion control algorithm and segment loss recovery techniques they use. One of the techniques is TCP NewReno. In this paper throughput analysis of a simple stochastic model for TCP NewReno is described as a mathematical relation of time that it takes for a signal to be sent plus the length of time it takes for an acknowledgment of that signal to be received and also loss behavior which is based on some previous work done over TCP Reno. It has dissimilarity in three characteristics: model for fast recovery, formulation of timeout behavior, and use of loss event. Here a two-parameter loss model is used that can better represent the diverse packet loss framework encountered by TCP on the Internet. The significant performance advantages of TCP NewReno over TCP Reno are shown using the ns-2 simulator. This performance evaluation is considered in case of two queue management mechanisms-DropTail and RED. The main outcomes from the experiments are: 1) In a wide range of network conditions for TCP NewReno there is an analysis of proposed model which can exactly forecast the stable state throughput 2) At the time of congestion TCP NewReno perform better than the Reno and 3) The packet loss against time during data transmission suffers from less loss rate than the existing Reno model.","PeriodicalId":240329,"journal":{"name":"2016 3rd International Conference on Electrical Engineering and Information Communication Technology (ICEEICT)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126454906","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}
