Heterogeneous Network (HetNet) technology is designed to be highly adaptable in subscribers' homes to provide high data rate communications with good quality of service. Femtocells are the indoor nodes of HetNet. Efficient handover of calls is the priority for successful femtocell/macrocell joint transmission. Handoff of femtocell-to-femtocell handover is the most visible challenge for dense deployment of nodes. This particular handover needs minimum as well appropriate neighbouring cell list which is needed for its successful operation. In this paper, we proposed an algorithm for dense femtocells deployment, i.e., an algorithm to create an optimized neighbour cell list with minimum number of femtocells (including the reduction of interfering femtocells and finding hidden ones). An appropriate and optimal neighbour femtocell list is mandatory for the much needed dense femtocellular network deployment in the near future. Therefore, reducing the size of the neighbour femtocell and making the list more efficient results in minimizing the amount of scanning and signal flow of mobile station during handover.","PeriodicalId":335492,"journal":{"name":"8th International Conference on Electrical and Computer Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120976357","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 expression of the conditional bit error rate (BER) for a given timing jitter is developed and the average BER is found by averaging the conditional BER over the probability density function of the timing jitter which is considered to be zero mean Gaussian. The results are evaluated at a bit rate of 2.4 Gbps over weak turbulence with Avalanche Photodiode (APD) receiver for different order of M-PPM modulation. It is found that there is significant deterioration in BER performance with increase in timing jitter variance and results in BER floor at higher value of jitter variance for a given M-PPM order and APD gain. Further, it is noticed that higher order M-PPM system suffer less than lower order PPM system at a given system BER. The analysis can also be useful for evaluating the impact of slot timing jitter for M-PPM FSO system with strong turbulence.","PeriodicalId":335492,"journal":{"name":"8th International Conference on Electrical and Computer Engineering","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126769385","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}

Recently a new method is established to generate power from the lost energy of a human during his/her locomotive period. A piezoelectric sensor based costly product is available in some developed countries which can generate power from human locomotive force, but it is not suitable for countries like Bangladesh where power demand is very high but economy is not highly developed. In this paper we will explain the design and construction method of a “Power Generating Slab” which can be used to generate power by establishing anywhere of the walking zone of human (roads, stairs, pavements, dais etc). This is done in a low cost process with locally available equipments (micro-generator, iron plate, rack pinion gear, free-wheeling system, spring etc). These slabs can easily sustain human weight when people walk along them. With a small deformation of spring, the weight (mechanical energy) of a human body is converted into electrical energy by rotating a micro-generator with the help of a `rotating shaft' coupled with it. From each foot step almost 10V-12V is generated. This energy is stored in a rechargeable battery which can be used as a power source to drive loads. Assembly of some power generating slabs can give better result. This is a method which is reusable and it will run for a longer period.","PeriodicalId":335492,"journal":{"name":"8th International Conference on Electrical and Computer Engineering","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124751457","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}
