In this paper, we compare fast and simple multigrid methods: V-Cycle, W-Cycle, and F-Cycle to solve Poisson Equation (PE) in polar plane coordinates. The solver is analysed toward different 2n + 1 grid sizes to evaluate its convergence properties, i.e. precision and accuracy, as compared to reference problem of cylindrical annulus. Each multigrid cycle is evaluated based on computation time, convergence error, and relative error. The results show that W-Cycle (γ = 4) gives more optimized solution as Poisson solver in comparison with the other multigrid methods.","PeriodicalId":428512,"journal":{"name":"2015 9th International Conference on Telecommunication Systems Services and Applications (TSSA)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128197927","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 19 channels are time multiplexed then mixed with the speech to produce a transmitting signal. In the receiver side, speech and EEG are separated by filtering. Based on simulation result in the noise environment, the proposed system has successfully separated the speech and the EEG signals. The correlation coefficient between the received signals after separation and the original ones are more than 0.8 for EEG and more than 0.7 for speech in 30 dB SNR.

One of the unique characteristics of CDMA system is that it is possible to trade off between capacity and its coverage, called the cell-breathing. Open loop and closed loop power control can be used to increase the capacity of CDMA system; while admission control can be applied to trade-off between its capacity and the coverage. Computer simulation was conducted to evaluate the power control performance in Rayleigh fading channel. Then semi-analytical evaluation was performed to obtain the coverage-capacity trade-off. The result shows that the capacity of CDMA systems increases when power control was employed. Numerical and semi analytical evaluation show that CDMA coverage and capacity can be traded-off to meet various demand of traffic capacity and cell coverage in rural environments.","PeriodicalId":428512,"journal":{"name":"2015 9th International Conference on Telecommunication Systems Services and Applications (TSSA)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129957129","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 scheme is also well known as Internet-of-Things (IoT) concept. Those two environments are connected to each other by using access point bridge. WSN system is established from efficient and scalable WSN components. Each component of WSN is designed to use an optimized protocol. WSN components are connected to each other in mesh topology in order to provide scalable architecture for further extension and changes. For outdoor environment, the existing internet-cloud system is used as infrastructure. Thus, this smart home platform can be monitored and controlled from smart phone, anytime and anywhere, as long as mobile data access is provided.

As standardized, fixed WiMAX uses OFDM as its physical air interface. Therefore, it also suffers from high PAPR. To solve this problem, Partial Transmit Sequence (PTS) is used in this paper due to its better performance among other PAPR reduction techniques. Unfortunately, in conventional PTS, an exhaustive search over all combinations of allowed phase weighting factors is needed. This process leads to high computational complexity. Hence, Grouping Phase Weighting (GPW) is used to simplify search complexity and still maintain to provide effective PAPR reduction as conventional PTS. The simulation is conducted to IEEE 802.16d system with various mandatory modulation types and channel coding rates. The derived results show that the choice of modulation type does not give significant effect on the PAPR reduction. The higher channel coding rate gives higher PAPR reduction.","PeriodicalId":428512,"journal":{"name":"2015 9th International Conference on Telecommunication Systems Services and Applications (TSSA)","volume":"263 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121204675","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}
