Rapid urbanization and proliferation of communication devices has made these telescopes vulnerable to increasingly high levels of Radio Frequency Interference (RFI). This has necessitated development of algorithms for the mitigation of the effects of RFI either in real time or during post processing. The performance of different algorithms can be verified using RFI emulator. The paper proposes a programmable and versatile RFI emulator architecture optimized for hardware platform for generating the signals with different types of interference as received by the wide-band signal processing chain. The design parameters for this RFI emulator have been arrived at as an optimal trade-off between the functional requirements and hardware utilization. The implementation of RFI emulator has been carried out on FPGA and the results of built-in testing of RFI mitigation logic using RFI emulator are provided.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133226041","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}

This paper examines the performance of DFIG under three cases viz., i) generator speed, ii) reactive power demand from grid and iii) wind speed. Based on the above disturbances, the system performance is analyzed by considering the parameters like rotor speed, generator torque, stator and rotor voltages and powers. It is also aims to explain DFIG as a vital dynamic reactive power source without the use of any additional external reactive power devices. The simulation results illustrate the efficacy and robustness of torque, speed and stator reactive power control for DFIG system by the proposed methodology. The torque surges are minimum even there is sudden change in wind speed, torque ripples and speed surges are not there when there is sudden change in wind speed.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"307 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133889233","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}

This paper analyzes the performance of a CDMA WSN, in terms of lifetime of the network, where nodes are placed in a random fashion. A routing protocol is proposed and simulated where selection of intermediate nodes is governed by a parameter which combines the estimation of detection probability of neighbors in presence of large scale fading, and maximum advanced distance with respect to the final destination. Further, the proposed routing scheme is modified by incorporating route diversity. Lifetimes are analyzed in both the cases and compared. Effects of detection probability, shadowing, and route diversity on lifetime are investigated.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"43 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114023579","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 features of MANETs are like open media, dynamic changes in topology, cooperative and collaborative algorithm and no centralized monitoring system. These features make the network more prone to malicious attack. The traditional way of protecting networks with firewalls and encryption software is no longer sufficient and effective for those features. In this paper, we present a new cluster based intrusion detection algorithm that takes care of black hole attacks in a MANET. This proposed algorithm is based on trustworthiness of the nodes in a network. The network is considered to be a layered structured. The nodes are member of a cluster. Each cluster has cluster head that takes care of all the members of its own cluster and communicates with cluster head at layer 2 whenever required. The cluster head at layer 2 communicate with all cluster head at layer 1. The selection of cluster head depends on three parameters battery power, mobility and trust value of a node in a cluster. Periodically the cluster head updation is done according to three parameters. We have implemented our algorithm using the NS simulator. The performance of the proposed Intrusion Detection System (IDS) has also been evaluated in the process. The performance graph shows marked improvement as far as packet dropping is concerned.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122367303","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}

Noise removal is given priority in existing denoising methods. In order to increase the visibility of structural details, contrast enhancement methods has to be used. In proposed method, a non-linear adaptive Gaussian denoising filter removes noises from the DTI. To increase the visibility of filtered micro structural details, a contrast enhancement method is also used. The proposed method is compared with the existing scalar Partial Differential Equation (PDE) and non local means (NLM) denoising methods. Quantitative measures are used for validating the efficiency of the proposed contrast enhancement method. The experiment results shows that the proposed method outperforms the scalar PDE method and NLM method.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123053495","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}

Conventionally hall sensors have been used to derive commutation instants. Use of position sensors has its own merits and demerits. In order to overcome the limitations of position sensor based drives, sensorless techniques are used for control of BLDC motor. The detection of the zero-crossing of the back-EMF is a widely used method for sensorless control. The commutation instants are derived from the information of zero crossing point of the back EMF. Several algorithms have been proposed in literature for the detection of back EMF zero crossing. In this paper a novel method for determining the commutation instants directly from the comparison of the line-to-line voltages and their difference voltages is presented. The performance of the BLDC drive with the proposed algorithm is studied and verified through simulation done in MATLAB/SIMULINK environment.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123964525","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}
