The interleavers are, therefore, referred has the heart of IDMA Transceivers. In the literature, researchers have proposed Tree Based Interleaver (TBI) which not only reduces the bandwidth requirement in comparison to that required in case of Random Interleavers (RI) but also reduces computational complexity drastically when compared with that of power interleavers. The memory requirement at receiver end and its cost problem are also solved by tree based interleaver with further reduction of the amount of information exchange between mobile stations and base stations required to specify the user-specific interleavers. In this paper, the performance analysis of iterative IDMA receivers have been evaluated with BPSK & QPSK modulation techniques employing tree based interleavers and random interleavers in uncoded and rate 1/2 covolutionally coded conditions with Additive White Gaussian Noise (AWGN) channel. During the simulation, it has been observed that IDMA system with QPSK modulation techniques employing TBI outperforms its counterparts optimally.","PeriodicalId":294850,"journal":{"name":"2011 International Conference on Communication Systems and Network Technologies","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115101849","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}

Location-based services are becoming popular for mobile users. The mobile users' location plays a key role to provide the service from one side, but it other side it is dimension of their privacy, so it necessary to keep the user information anonymous to the other parties. Since one important issue in LBS is to achieve an accurate service, hence it is important to use the mobile user accurate location. Using the location accurately raises some concerns on behalf of the user's privacy. One solution for meeting this requirement is using by the means of a anonymizer. Anonymizer uses K-anonymity cloaking the user location to K-anonymizing spatial region (K-ASR). Traditional K-anonymity method needs complex query processing algorithms at the server side and have drawback of tracking user. In this paper we have proposed a new model for mobile users to retrieve the result quickly and increases user's privacy.","PeriodicalId":294850,"journal":{"name":"2011 International Conference on Communication Systems and Network Technologies","volume":"369 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126707031","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}

Selection operator has got the force that may pull the search to a narrow area of search space or it may lend the algorithm to search the entire search space. This work focuses attention on the selection stage of multi-objective Genetic algorithm (MOGA) used for solving multi-objective optimization problems. Here we propose an improved selection scheme along with summation of normalized objective value based sorting. The algorithm is tested on test problems of CEC09 competition. The proposed algorithm SNOVMOGA (Summation of Normalized Objective Value based Multi-objective Genetic Algorithm) has shown either comparable or good performance on few unconstrained test problems.

Manikandan","doi":"10.1109/CSNT.2011.155","DOIUrl":"https://doi.org/10.1109/CSNT.2011.155","url":null,"abstract":"Communication systems are considered as one of the major requirements for the current and next generation fighter aircrafts to complete a mission successfully. Efficient net-centric warfare and situational awareness can be achieved with modernized communication system and high-end sensors. The conventional communication systems available consist of individual systems for each functionality. In such cases, the failure of one system leads to failure of the functionality of that system and the mission has to be completed without that system. Hence there is an urge to develop a state-of-the-art on-flight software reconfigurable communication system to provide better redundancy, successful completion of mission and efficient utilization of systems on-board for fighter aircraft. In this paper, the functionality of all the on-board communication systems is explained and the design of a state-of-the-art software re-configurable communication suite is proposed for fighter aircrafts. The highlight of this architecture is that the hardware resources are shared between the systems and incase of failure of one system, the other system shall be reconfigured on-flight to take up the functionality of the failed system. The software architecture employs software code reusability for easy debugging and code verification. The proposed system is based on the concept of Software Defined Radio (SDR) and the functionality is extended from hand-held radio to entire communication system of the aircraft.","PeriodicalId":294850,"journal":{"name":"2011 International Conference on Communication Systems and Network Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131265453","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}

Here, each of the designed sets of unipolar orthogonal codes is independent of other sets of unipolar orthogonal codes of same length, same weight, and with same or different number of codes. The results of the proposed algorithm are being compared with other one dimensional optical orthogonal code generation schemes presented in literatures. The unipolar orthogonal codes of any of the designed sets can be utilized for generation of optical signature sequences for assignment to users of Incoherent Optical Code Division Multiple Access (OCDMA) system for the purpose of spread spectrum communication over optical fiber.","PeriodicalId":294850,"journal":{"name":"2011 International Conference on Communication Systems and Network Technologies","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130763548","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}
